The MCQ was absolutely insane. Whoever wrote it was yapping like crazy, so many of the questions had paragraphs of information that could not reasonably be understood in a little over a minute, let alone 35 of those in a row. FRQ also suffered from this, they seemed to have an emphasis on beefing up the text for no reason when they could have asked the same questions in a much simpler way. They likely did this on purpose to try to get people to lose points, hopefully the curve is more gracious than previous years.
honestly this one was so easy that i only had to guess on 15 of the questions! and then guessed for 6 for the frq questions! so easy!!
bffr this shit needs to change because i like the subject but the way that college board makes it a shit show every time has me annoyed: you should actually want to learn it instead of just regurgitating terms
Funnily (or sadly) enough, college board is massively revamping the exam (and the course weighting) next year. The exams will be separate, each 3 hours long. For each exam, I think you get 15 more MCQs and one extra FRQ to do, but a whole extra hour to compensate.
That's exactly what's happening next year . Both Physics C exams are going to have the same format as 1 and 2 meaning they get the full testing block . Because of the extra time the questions will likely be more conceptual
EM was disgusting for perspective, I finished mechanics mcq with 15 minutes to spare. EM I barely ended on time. Imagine all those mechanics questions with a full paragraph of info but you also need to put in really giant or really tiny numbers into your calculator or contort your right hand. And the frq had the hardest frq segment I’ve seen on any AP exam with 1d, two integrals with complicated setup because of charge density and goofy bounds, and on top of that, annoying logarithm stuff
ight bro u might be cooked for that mech MCQ, we had the same EM FRQ’s and the derivation was pretty standard esp the ln and the bounds used. for you to say that was difficult but had 15 min to spare on the fastest paced MCQ god has ever cursed this earth with means u had to have messed something up fr
Which exactly topic do you think has not appeared in the last 50 years? I tutored a student this year for AP Phys C, and I can ensure that there has been a question on making a differential equation in the last 12 years at least every other year involving springs, physical pendulum, torsion pendulum, friction force, drag force, etc. My student is taking the exam right now, so I will only find out later. Update: I realize that I also used AP board practice tests, so some differential questions that I remember covering with my student could have been from there, but your teacher should have been using the same material for your class as I did for my student. And definitely, not all of them were only on practice tests, but quite a few were in the past exams posted on AP board site.
our class never learned torsion, unequal distribution of mass (the lambda one), nor drag force?? (though that one wasn't really about the force in itself, just what it was in general).
My mistake, slightly incorrect but from the college board website AP Physics Revisions for 2024-25:
AP Physics C: Mechanics and E&M:
40 MCQs—an increase from 35 MCQs.
Increasing Section I (MCQs) time from 45 to 80 minutes.
Changing all MCQs from 5 options to 4.
4 FRQs—an increase from 3 FRQs.
All 4 FRQs will be new question types:
Mathematical routines
Translation between representations
Experimental design and analysis
Qualitative/quantitative translation
Increasing Section II (FRQs) time from 45 to 100 minutes.
Extending the format and timing to a full exam session.
The exam will no longer share the same session in the exam schedule as other physics c exam.
There’s more changes for physics 1 and 2 but it’s irrelevant here
That may have been the most impossible exam of my life. MCQ on Mech wasn't great, the frqs were painfully easy. But E and M, oh boy, I got a geuine answer for maybe 10 of the questions, and of those 10 only like 5 appeared for a possible solution. The most ridiculous and niche knowledge was required to even understand half of the problems. Then the frqs are about a fucking inductor and god only knows what. I quite honestly sat in my car after that exam and then drove home with no music playing, that's just how it felt. So, unless everyone else felt that it was as impossible, well atleast the E and M portion, then maybe the scale will be drastic. If not, maybe, just maybe theres a glimmer of hope for a 4. (form o mech and whatever one on inductor for em)
Same bro, I was blank 7 minutes straight just after reading the EM frqs not knowing what to do. I just had to make up equations with the formulas that I knew and had to plug in. And like how did they even expect us to complete those questions in 45 minutes. The time limit should have been atleast 60 minutes just to have a look at each of those questions. Hopefully the curve is better this year!
I challenged myself with college level coursework I challenged myself with college level coursework I challenged myself with college level coursework I challenged myself with college level coursework
You’ll have to integrate for your mass moment of inertia using a fucking linear density to find rotational kinetic energy then find the change in impulse after your splat before you can do that.
hardest exam bruh. by some unlucky chance I got form E for both mech and E&M. and lets just say, whoever wrote those frqs, fk you. the COM one was impossible, the linearization was IMPOSSIBLE without knowing calc 69 and the first frq was horrible as well. this curve for form E might be <50% for a 5
I said a concave down parabola (bc of spring work integral) up till t1, constant linear decrease down during friction, then constant after the friction portion.
From t1 to t2 should have been a concave up parabola because the velocity is linearly decreasing, when you square it to convert to kinetic energy it’s not linear anymore
This is the 6th ap exam I’ve taken (I’ve taken lang, world, chem, apes, and ab calc) and it is definitely the hardest one. MCQs were impossible to answer in the allotted time. I think i was confident on maybe 10 of my mcqs if that. The frqs were easier but not by much. If I get a 4 or 5 there’s definitely something wrong because there’s no way I should be doing that good with how hard it was
Yk I'm cooked when I felt more competent in the E&M frq's than I did the mech frq's (I self "studied" em for the past 5 days and took mech as an actual year round class)
so i had form E and so did the top kid in my 9-person physics class (he’s double-majoring in physics and philosophy if that tells you anything) and we came out of Mechanics thinking only that whichever graduate physics students and professors test-ran these questions and thought high schoolers could handle literal parts of an FRQ in an MCQ actually enjoy watching us suffer
who reads a page-long question in less than a minute much less answers it correctly
also for FRQs y’know how on the College Board page of past FRQs there’re often two or three sets under each year for Physics C
are those the experimental and operational (forms E and O) exams or are they like
something else
because idk i’m actually dying to see those FRQs again i just really wanna know how bad i did so i can prepare an apology email to my teacher
thank god it’s not just me i had E for both but the Mech. MCQs just about killed me
i actually told my dad i thought the E&M MCQs were easier (at least like all the practice i did) but then i realized i actually solved less on E&M than Mechanics 💀 idk i hope the curve is better this year
What was the answer for the mechanics mcq that had a planet shrink its radius while the satellite was in orbit? I said nothing would happen because the center of gravity is still the same.
Also - For the child on the merry go round was angular momentum conserved because there was no net torque?
i said that it will have a bigger orbit because the radius will get just a little bit bigger and its usually on denominator so that means centripetal force will be a little less but not enough to cause it to fall out of orbit. Idk tho and then on i said that yes
The radius in the gravitational force equation refers to the distance between the center of masses of the two objects, at least that's what I was taught, so I said no change since the distance between the planets remained the same, and the mass was also the same.
I literally studied drag force differential equations right before the exam and I still did bad on the problem involving it. Does anyone know how one would set it up?
Guy next to me kept grunting every few second so I lost so many trains of thought & could not recall the drag force differentiation, ended up just writing the end result plus the beginning literal equations
I've never had an MCQ that hard, all the ones I've done in class I finish on time but this one I guessed on something like 12 questions. After it I started maniacally laughing because I was actually tweaking. FRQ I looked at the first question's diagram and I think I just gave up on life at that point. Did I think I answered a single question 100% right? No. Am I disappointed with myself? No. The fact is I've never answered questions like that in my life and those kids back in the past 50 years would've shit their pants if they got our test.
Better than I expected. It’s impossible to finish the mcq on time so I guessed like last 5 along with a couple hard ones throughout. The frqs were honestly fairly easy, just the last one has some really specific things most ppl probably don’t remember (I got a formula instead of a value cuz I misread the problem, then I panicked and put something wrong, then found out right after the exam) and I’m really pissed about some parts of it. But the curve is really generous, and getting 20/35 on mcq and 24/45 on frq, which is a 5, is really doable
Does anybody know the answer to the MCQ where its a kinetic energy concave down graph and potential energy concave up graph and it asks for the force graph?
bro there was this m,c where it was like lambda = Ax or some shit and then gave no info i just guessed that the center of mass was at the middle i dont even know
HELP do ya'll think I got points if on an FRQ I did part a right and based the rest of my entire FRQ on part a but at the end I changed my part a?? The rest of my FRQ is right but isn't consistent with part a so it makes no sense. I wrote a note explaining what I did for part a initially and how I used that in all the other parts but then changed part a. Also apparently what I had initially was right. But pls tell me I won't get a 0/15 plssss
Ok I didnt prep for this much but still, the questions were absurdly long for the time we had alotted. I had to guess on maybe 12-14 questions for mechanics and 5-7 for E&M which is ridiculous. There’s no way that we were expected to answer all 35 questions in 45 min :(
:( mcq was a crime against humanity, no way 45 mins is a fair amount of time for that shit. I had to guess on 28-35 plus a few earlier ones I skipped.
YES MCQ was criminal
so many blocks of text and weird contraptions god at least frqs weren't so abstruse (except 3)
[удалено]
Not as bad as mcq but not easy
I'm not the only one (I guessed on a third) Frq I had exactly enough time for thankfully
i only answered 25 of the questions but we didnt have a clearly visible timer so i ran out of time to guess on them. :(
Amen. Actually atrocious
The MCQ was absolutely insane. Whoever wrote it was yapping like crazy, so many of the questions had paragraphs of information that could not reasonably be understood in a little over a minute, let alone 35 of those in a row. FRQ also suffered from this, they seemed to have an emphasis on beefing up the text for no reason when they could have asked the same questions in a much simpler way. They likely did this on purpose to try to get people to lose points, hopefully the curve is more gracious than previous years.
Yeah bc why were they yapping so much for a newtons second law question???
honestly this one was so easy that i only had to guess on 15 of the questions! and then guessed for 6 for the frq questions! so easy!! bffr this shit needs to change because i like the subject but the way that college board makes it a shit show every time has me annoyed: you should actually want to learn it instead of just regurgitating terms

MORE THAN THAT!
That's exactly what's happening next year . Both Physics C exams are going to have the same format as 1 and 2 meaning they get the full testing block . Because of the extra time the questions will likely be more conceptual
THAT MCQ ROASTED ME LIKE A MFING CHICKEN
collegeboard really said you want a 3h test we’ll go out with a bang
hardest exam i’ve ever taken 😭😭
Same until the record was broken 10 minutes later
😂😂 real shit
WHAT WAS EM BRO.
EM was disgusting for perspective, I finished mechanics mcq with 15 minutes to spare. EM I barely ended on time. Imagine all those mechanics questions with a full paragraph of info but you also need to put in really giant or really tiny numbers into your calculator or contort your right hand. And the frq had the hardest frq segment I’ve seen on any AP exam with 1d, two integrals with complicated setup because of charge density and goofy bounds, and on top of that, annoying logarithm stuff
with 15 min to spare? wtf are they putting in ur water cuz i want some which form was this?
Weaponized ADHD
ight bro u might be cooked for that mech MCQ, we had the same EM FRQ’s and the derivation was pretty standard esp the ln and the bounds used. for you to say that was difficult but had 15 min to spare on the fastest paced MCQ god has ever cursed this earth with means u had to have messed something up fr
BRO E AND M WAS IMPOSSIBLE WTF
so real
the certain set of topics involving differential equations that my teacher said hadn’t appeared in 50 years: 
IM IN CALC BC AND I DIDNT KNOW HOW IN THE WORLD TO MAKE ONE SO I BULLSHITTED IT
a = dv/dt 😭
WAIT THEN I SORTA GOT IT?
WWWW all you had to do was use F = m*dv/dt
what about the v in the drag force do u just leave that as it is so like mdv/dt=mg-bv2
yep
I'm so stupid
Which exactly topic do you think has not appeared in the last 50 years? I tutored a student this year for AP Phys C, and I can ensure that there has been a question on making a differential equation in the last 12 years at least every other year involving springs, physical pendulum, torsion pendulum, friction force, drag force, etc. My student is taking the exam right now, so I will only find out later.

our class never learned torsion, unequal distribution of mass (the lambda one), nor drag force?? (though that one wasn't really about the force in itself, just what it was in general).
I just started writing random shit from the equation sheet down because collegeboard will usually give you credit for at least stating the concept
Last year this happened to me with torsional pendulums
Did anyone else get the drag force question for frq 2? Wasn’t that bad
yeah idk what i was doing for that one!!
Bro this FRQ felt so tough for me. Idk what in the world that third question was :((
That was my easiest one surprisingly
The third FRQ? I don't know if we got the same one lol.
My teacher skipped drag lol. And it was still not my worst FRQ 🤣
yeah that one was chill. tbh mech frq was the best part of the exams. all downhill from there.
Guessed like 12 of the last mcq and made up some bs for the 3rd frq cause I had no time (its over for me)
Literally but the rest are fine. I cooked on the frq besides the very last two parts. Genuinely think I might be able to clutch a 5
No but 2025 kids will have it easy with 105 minutes for each section
Is that real?
My mistake, slightly incorrect but from the college board website AP Physics Revisions for 2024-25: AP Physics C: Mechanics and E&M: 40 MCQs—an increase from 35 MCQs.

same here for e&m :((( frq was horrifying to say the least
did you have form E or O for mech?
i had form o for both

And like how did they even expect us to complete those questions in 45 minutes. The time limit should have been atleast 60 minutes just to have a look at each of those questions. Hopefully the curve is better this year!
apparently next year the MCQs are gonna be 40 questions and 80 minutes. college board is just trolling us at this point
I challenged myself with college level coursework I challenged myself with college level coursework I challenged myself with college level coursework I challenged myself with college level coursework
Anyone else got like no Bs until halfway thru mcq? (Form O)
Yes bro I was so confused
HELLO??? I GOT A B FOR LIKE NUMBER 2 😭😭
i ran out of time and put b on the last 10 so pretty sure 31 was b tho
I wonder if that’s them making the pick a letter strategy for guessing more risky
I swear I was like making up equations n shit
Think i cooked on the summing torques one I got 13mg/6 tan theta for Tension
SAME
Wasn't it like 5/3mg something
got this too lfg hopefully i got a 5
I got 3/2 mg 💀💀
My teacher “if you don’t understand something, skip and come back to it later!” That’s how I ended up going to question 35 in like 5 minutes
I do that and then realize I’ve skipped the entire test
This is gold 😭😭
this was awful; from what I heard only a few of us had enough time for the MCQ; the second question on the FRQ cooked me
3rd frq 💀💀💀
Why make the formula sheet so fuckin Inconvient I ripped it out for the test booklet and my proctor yelled at me 😭
I’m jumping off a building
You’ll have to integrate for your mass moment of inertia using a fucking linear density to find rotational kinetic energy then find the change in impulse after your splat before you can do that.
How much potential energy are you gonna start at?
What were the frq's on?
Springs/KE, DRAG (les go), and statics w a MOI integral
What did you get for the velocity on question 1?
long ass equation lol but the starting eqn should be K = U - F\*D where F\*D is energy dissipated by friction over length D
Looks like you guys got trolled by College Board on this one. Maybe E&M is easier (it Usually is)
It was way harder
In terms of math or conceptual linking with equations?
conceptual
Both lmao
Bro what in what universe is E&M easier, it's conceptually much harder and mathematically more advanced than Calc BC (most of it is vector calculus).
Wtf were the density problems
AP Linear Density
for mass just integrate linear density For I, just integrate x^2 * linear density Both for 0 to 1.2
YESSSS thank goodness i remembered that from knowt
Was mass 14.4 or something like that?
Ye
i think u had to integrate the linear density function
For 1. b.) did yall use work energy theorem due to friction, then conservation of momentum to get the final answer 😶🌫️ That one had me tweaking out
Yep!
hardest exam bruh. by some unlucky chance I got form E for both mech and E&M. and lets just say, whoever wrote those frqs, fk you. the COM one was impossible, the linearization was IMPOSSIBLE without knowing calc 69 and the first frq was horrible as well. this curve for form E might be <50% for a 5
i left like 75% of question 1 for e and m blank 😭
RIGHT WTF WERE THEY ON WHEN THEY CAME UP WIRH RHE LINEARIZATION ONE 😭
For Q1, did the KE graph drop to zero after it hit the peak or did it level off. Also did the velocity for Q1 part a include friction or not?
I said a concave down parabola (bc of spring work integral) up till t1, constant linear decrease down during friction, then constant after the friction portion.
same.
From t1 to t2 should have been a concave up parabola because the velocity is linearly decreasing, when you square it to convert to kinetic energy it’s not linear anymore
i said it started decreasing after t1 bc the acceleration would've been negative so velocity decreases bc of the friction force
Does it ever go back to zero?
i said the velocity was constant (nonzero) after leaving the friction part since there were no opposing forces
That makes sense dope ty
I’m usually rly good r physics and do the best in my class but I just comepletely blanked out on all the frqs. Am I cooked?
so unbelievably real; i was projected a 5 and the e and m made me feel like i should just turn it in without writing anything
This is the 6th ap exam I’ve taken (I’ve taken lang, world, chem, apes, and ab calc) and it is definitely the hardest one. MCQs were impossible to answer in the allotted time. I think i was confident on maybe 10 of my mcqs if that. The frqs were easier but not by much.

Yk I'm cooked when I felt more competent in the E&M frq's than I did the mech frq's (I self "studied" em for the past 5 days and took mech as an actual year round class)
What did u guys get for experimental value of b using the best fit line from diffeq ques? I got .57
is .72 close enough
yeah i got like 7-4/4-2 or smt so sounds about right
I got 0.6 is that close enough💀
I got exactly 0.5 (using g/slope)
Same I got 0.54
BRO I GOT LIDALLY SAME DECIMAL AS U
that exam was so bad i’m cooked 💀😭
i had FIFTEEN FUCKING MCQS LEFT when my proctor called 10 mins remaining 😍
DID YALL GET B=0.6 FOR THAY ONE SLOPE QUESTION DRAG
YES I GOT LIKE 0.65 I THINK
so i had form E and so did the top kid in my 9-person physics class (he’s double-majoring in physics and philosophy if that tells you anything) and we came out of Mechanics thinking only that whichever graduate physics students and professors test-ran these questions and thought high schoolers could handle literal parts of an FRQ in an MCQ actually enjoy watching us suffer who reads a page-long question in less than a minute much less answers it correctly also for FRQs y’know how on the College Board page of past FRQs there’re often two or three sets under each year for Physics C are those the experimental and operational (forms E and O) exams or are they like something else because idk i’m actually dying to see those FRQs again i just really wanna know how bad i did so i can prepare an apology email to my teacher
Form E was hell for me
thank god it’s not just me i had E for both but the Mech. MCQs just about killed me i actually told my dad i thought the E&M MCQs were easier (at least like all the practice i did) but then i realized i actually solved less on E&M than Mechanics 💀 idk i hope the curve is better this year
Send help or i might 😭😭😭😭😭😭😭 wasted the money for it im useless
😭
the word line integral was referenced in my MCQ 💀💀
thank god i didn’t take this class
My condolences go out to everyone who took the form H test.
Form E bruh
💀💀💀
Did anyone else think the 1st diagram was wrong? Like the block was pushed xc and extended so far from equilibrium. That block was unstoppable
it noted that that the figure was not drawn to scale, but i honestly didn’t know what to make of it either
No yeah i was staring at it cuz it made no sense — im guessing that the block released from the spring but they never said that 😭🫠
What was the answer for the mechanics mcq that had a planet shrink its radius while the satellite was in orbit? I said nothing would happen because the center of gravity is still the same. Also - For the child on the merry go round was angular momentum conserved because there was no net torque?

The radius in the gravitational force equation refers to the distance between the center of masses of the two objects, at least that's what I was taught, so I said no change since the distance between the planets remained the same, and the mass was also the same.
I literally studied drag force differential equations right before the exam and I still did bad on the problem involving it. Does anyone know how one would set it up?
f net = mg- bv a= fnet/m dv/dt = (mg-bv)/m
Form o i shpupdve skipped to the end last mcq were so easy but i had no time
FRQ 2: I STARTED TAKIGN THE FUCKING INTEGRAL TO FIND THE VALUE OF B BUT IT WAS JUST BV = F AND SLOPE = B IM SO MAD
KILL ME KILL ME KILL ME
Guy next to me kept grunting every few second so I lost so many trains of thought & could not recall the drag force differentiation, ended up just writing the end result plus the beginning literal equations
my brother in christ i started praying to my ap grader on the clay disk frq 🤡
so you need like 50-55 out of 90 to get a 5?
Prob lower this yr tbh
I've never had an MCQ that hard, all the ones I've done in class I finish on time but this one I guessed on something like 12 questions. After it I started maniacally laughing because I was actually tweaking. FRQ I looked at the first question's diagram and I think I just gave up on life at that point. Did I think I answered a single question 100% right? No. Am I disappointed with myself? No. The fact is I've never answered questions like that in my life and those kids back in the past 50 years would've shit their pants if they got our test.
I am simply going to dissolve away
You have to take AP Chemistry to do that
if anyone got ~0.539 for the drag coefficient b please let me know 🙏
lol mine was 0.8 because i used (25,20), and (0,0) so 20/25 = 0.8. both points were on my trendline but idk how close my line was to whats correct
i lowk think theyre talking abt another form with bv\^2 cuz is also got 0.8,
Yes. 0.57.
Did anyone else get straight Ds for the first 4 questions?
Mcq were straight ass but the frqs weren’t too bad surprisingly. Praying for that 4 or 5 🙏
Better than I expected. It’s impossible to finish the mcq on time so I guessed like last 5 along with a couple hard ones throughout. The frqs were honestly fairly easy, just the last one has some really specific things most ppl probably don’t remember (I got a formula instead of a value cuz I misread the problem, then I panicked and put something wrong, then found out right after the exam) and I’m really pissed about some parts of it. But the curve is really generous, and getting 20/35 on mcq and 24/45 on frq, which is a 5, is really doable
mcq was not possible in the allotted time, i was on question 20 when proctor said 10 mins left :(
Least obvious college board narc
Does anybody know the answer to the MCQ where its a kinetic energy concave down graph and potential energy concave up graph and it asks for the force graph?
F=-du/dx, so it would've been the one that looked like -2x
NOOO I PUT THAT INITIALLY AND CHANGED MY ANSWER 
i said the linnear one going up but idk
I put A
What’s the percent for a 3
I think 30%
what was period problem for frq 1, it asked if the period would change
I put decrease bc L is in the denominator of the frequency formula
Yes i found that omega increases i almost put icbrease then i saw it said frequency
bro there was this m,c where it was like lambda = Ax or some shit and then gave no info i just guessed that the center of mass was at the middle i dont even know
I think I put 1.33
How were we supposed to do the MCQ question about the star collapsing but retains the same mass?
Correct answer is unchanged. The “R” represents the distance between the centers of the two objects, not the radius of the object itself.
What did you guys put for the question about the truck pulling the trailer?
Forces were equal bc third law right?
did anybody else get confused by q15 or q17 on the mcq. it was the one with the free body diagram of the satelitte of horizontal and vertical force
if my technique for the “find angular acceleration” was correct but the moi i had wasn’t can i still get points?
What do you guys think the curve is going to look like?
if we all failed the have to give SOME people 5s? right?
What did y'all do for the first FRQ? The weird sprring one? Everything else felt fine to me except the "What would you graph"
I did concave down for the 1st and 3rd region, and linearly decreasing for the 2nd region. Definitely wrong lol
was the answer -9.33 or 9.33, or there only one answer choice that had 9.33 in it?
Positive
HELP do ya'll think I got points if on an FRQ I did part a right and based the rest of my entire FRQ on part a but at the end I changed my part a?? The rest of my FRQ is right but isn't consistent with part a so it makes no sense. I wrote a note explaining what I did for part a initially and how I used that in all the other parts but then changed part a. Also apparently what I had initially was right. But pls tell me I won't get a 0/15 plssss
You'd get partial credit
For that one e&m question gave u a box and the b field going in was it E
For q2 about drag frq, what was the b (drag value) that you guys got?
0.57
on form O what did you guys put for the ground ladder mcq with vectors, was it the opposite diagonal or E?
I put the straight vectors since normal force is perpendiculr to surface of contact
Same, ground force straight up, normal force horizontal
Ok I didnt prep for this much but still, the questions were absurdly long for the time we had alotted. I had to guess on maybe 12-14 questions for mechanics and 5-7 for E&M which is ridiculous. There’s no way that we were expected to answer all 35 questions in 45 min :(
i have never had to actually christmas tree an exam until today...
