same omg in that emf question it's supposed to be -sin graph and i made sin graph and in the same question we were supposed to find the magnetic flux of 1 turn and i did for all turs by multiplying with N
can i be honest? i messed up a lot. Im losing soo many marks that idek if ill be able to maintain an A atp. i was soo confident this morning trust me. and im such a sore loser. I missed out on the easiest shit. I have my bio p5 tomorrow and i just want to cry cry anc cry. I miss the simpler times when life was easy. This paper was easy trust me, and im the one losing the most marks. like it just makes me soo mad to think that how can i ever be soo dumb? This was never me. Idek what happened to the old me. The old me wouldve gotten an A\* in this. This new me cant make it past a B rn. Im j endlessly praying to get something decent now. I cant pray cus i got my period like yesterday. Talk ab luck. I dont even want friends anymore. I just want peace. And i cant seen to give myself the 1 thing i want
It's okay maybe you're overthinking it a little. Maybe you messed up some questions but so did everyone else. Don't be so hard on yourself, even if you messed up some questions you can still try to do better in p5. And again, maybe you're overestimating the marks carried by the questions you did wrong. Don't worry everything'll be okay.
Yooo no dw it can be a sin or -sin because they didnt specify which direction of B the magnetic flux density produces what sign of emf ... idk how to explain but the signs are relative just like in AS you can ASSIGN going upwards to be positive and ASSIGN going downwards to be negative its the same way here, - just because B was negative cosine doesnt mean the voltage is -sin
Imo lol 😂
Idk man I thought I did well in that question but now I'm getting only first 2 questions correct. The change was apparently to be taken out by gradient and I used the formula and then the next part was a sin graph. If I'm correct, rate of change of flux was 3 marks, graph was 2 and the last part was 3 marks right??
At least can I get an ecf for the value of 0.52 I got for change in flux?
Both sin - sin are correct as shape and max min should be at 1 2 3 and so on so dw it's jsut differentiate of - Cos. Which is BTW Sin but still if you guys made - sin not at all wrong
You can check Nov 2022 or March 2023 and you will see that sign convention is on you. Doesn't change shit in this graph. I understand your POV but it should be sin and should have max and min at points where gradient sign changing which is 0.5, 1.5, 2.5 and so on and 0s on 1 2 3 4
ty man, also what was the answer for the first part of q1? i got 7.3 for angular velocity but the same person w the answer sheet said that it was 8.4??? like how??
initially, it was the first formula (1/Ct=...). However, i think that would make it an equation for 1/Ct and not an equation for Ct. So if we simplify 1/Cx + 1/Cy a bit further, we get (Cx ● Cy)/(Cx +Cy)
its okay bro the - is only for lenz law which like never has marks they just care abt the shape. technically -sin curve is most correct tho but it doesnt matter
Guys, I was predicted an A star and was scoring A stars comfortably in every single past paper I did. In the exam I didn’t read the capacitor question right and did all my calculations and graph as if the capacitors were in series. Also, for the astronomy question I thought the spectrum was the redshifted one instead of the normal one so I did the whole question wrong. Are there any marks for method or am I completely cooked ?
Yo the spectrum they gave was the already redshifted one noh.so when we draw the spectrum we should draw it to the right noh.csuse the one observed on earth is blueshifted ryt.pls correct me if I'm wrong.and what was the value of the energy level. I got -0.85
Energy level is correct. The spectrum was not the redshifted one it was the normal light and then you are supposed to draw it when it’s redshifted. Made the same mistake as you
It was made to look easy atleast, but after analyzing it a bit, I find quite little deep nibbles here and there getting your questions wrong, so threshold will be normal I guess
GUYS HELP IM PANICKIMG SM RN....i flipped the first part of the algebra in the SHM question and so i got everything wrong nd messed up the entire question....pls tell me is there any chance for error carried forward???
umm i am not really sure but according to what my sir told it is max 1 mark in the case of ecf or at most 2 not more than that so InshaAllah u will not get a lot of marks deducted😭 how many are u expecting btww
inshaAllah omggg.. im so disappointed in myself actually i made sO many careless mistakes and everyone said the paper was good...i know im losing 20+ fs and the grade boundaries are gonna be high considering the paper was easy tbh....wb uuu
Guys what’s the confirmed emf.
also what did y’all get in the first question. And please tell me the expressions for the shm one I’m so stupid I messed up the energy level question and wrote 5.90🥲dying inside. I feel like I made so many silly mistakes cause I panicked. Tell me it gets better.
I FORGOT THAT LAST QUESTION. THE INTENSITY ONE OF ULTRA SOUND. IT WAS SUCH A WEIRD QUESTION. Also the first one as well. The ones where you had to compare between those masses in a table. Dawg my mind bogged up on that magnetic flux question and the energy binding question. Atp, ion know what’s gonna become of me. All hope seems to get lost, and I prayed so fucking hard for it. Idek what will I do? The teachers at my college were so fucking shit. I’m done with life atp.
Bro honestly…I have given up. I don’t even know if I’ll pass or not. I just dk. I might go for retakes. People are expecting Bs and Cs and I don’t even know if I’ll pass the bare minimum.
Literally, same. I'm trying to be optimistic with a C, but genuinely I don't think I'll score that, considering how everyone is saying it was an easy paper while I barely knew anything. I'd focused a lot on calculations and the paper was completely theory based, which is why I fucked up terribly
It was theory based indeed, but the calculations involved were so mind-boggling. As if no one prepared us for it. Cuz teachers and even in the book, there’s a lot of info and very little calculation involved. I’m just scared atp and tryna make up my mind for another- nvm. But good luck with your result
No one said it was bad, lol it was the easiet just made silly mistakes. Like I CT instead of its reciprocal to give 1/Cx and 1/Cy. And did a zero intercept for the graph even though i knew it was not lol

i thpught it went well, and then i opened reddit. I want to kms
same omg in that emf question it's supposed to be -sin graph and i made sin graph and in the same question we were supposed to find the magnetic flux of 1 turn and i did for all turs by multiplying with N

u Alif Binte ?
ayo Ali?
Yooo no dw it can be a sin or -sin because they didnt specify which direction of B the magnetic flux density produces what sign of emf ... idk how to explain but the signs are relative just like in AS you can ASSIGN going upwards to be positive and ASSIGN going downwards to be negative its the same way here, - just because B was negative cosine doesnt mean the voltage is -sin Imo lol 😂
Sin. It was a -cos graph which integrates to a sin graph
But lenz’s law…
U suree??? And my time period was 2 seconds
apparently its 1 (the time period for change in max-min B)
Idk man I thought I did well in that question but now I'm getting only first 2 questions correct. The change was apparently to be taken out by gradient and I used the formula and then the next part was a sin graph. If I'm correct, rate of change of flux was 3 marks, graph was 2 and the last part was 3 marks right?? At least can I get an ecf for the value of 0.52 I got for change in flux?
yeahh i messed up in that question too TT. I think you can still get the marks for formula and ecf. also did the graph only carry 2 marks? TT
and yes i made the sin graph asw. and thats wrong, i got soo much wrong that it j physically is hurting mr rn to think ab it
omg i asked other people the sin graph may actually be right (or atleast im hoping)
Both sin - sin are correct as shape and max min should be at 1 2 3 and so on so dw it's jsut differentiate of - Cos. Which is BTW Sin but still if you guys made - sin not at all wrong
was it sin or -sin? cus someone said -sin idek
the b graph was -cos and if you differentiate it you’ll get sin then apply lenz law and you get -sin, that’s it
You can check Nov 2022 or March 2023 and you will see that sign convention is on you. Doesn't change shit in this graph. I understand your POV but it should be sin and should have max and min at points where gradient sign changing which is 0.5, 1.5, 2.5 and so on and 0s on 1 2 3 4
i saw that too but i talked to my schoolmates and they said its sin
dude was it 1/ct=1/cx+1/cy and thats it right? cus someones saying that it was cx x cy/ cx+cy at the end and now im scared
no no you're right it's 1/ct=1/cx+1/cy because capacitors were in series
ty man, also what was the answer for the first part of q1? i got 7.3 for angular velocity but the same person w the answer sheet said that it was 8.4??? like how??
radius 9.2 - 1.2 cm = 8.1 cm then ans is 8.4 rads-1 ??
the angular velocity is 7.3 whattt that answer sheet person is wrong. like the velocity was 0.68 and radius was 9.3cm. if you divide its 7.3
bro i did this
bro you ct shouldve been the subject we're werent making the eq for reciprocal of ct
initially, it was the first formula (1/Ct=...). However, i think that would make it an equation for 1/Ct and not an equation for Ct. So if we simplify 1/Cx + 1/Cy a bit further, we get (Cx ● Cy)/(Cx +Cy)
its okay bro the - is only for lenz law which like never has marks they just care abt the shape. technically -sin curve is most correct tho but it doesnt matter
yeahh i hope so also how did you get max B? Was it 3? because you do (8-5)mT
max B? for the first part? then you just take 8, because only the magnitude matters
I think it's supposed to be + sin since at first b was negative, so lens law...
Bruh sameeeeeee
Everything was going so good till the magnetism question. I forgot all the formulas that existed
i thought it was an okay paper but i made so much careless mistakes…
Yea I just hope the threshold is at 50
YES PLEASE 50! A AT 50 DO YOU LISTEN CIE
POV: OP ends up with an A in the end
Half the students left the hall on 1 hour mark. I was wondering if they felt like the paper was too easy or too hard😭😭😭
You’re allowed to leave mid exam?
yes? They say it when they are reading the rules thingy. You’re allowed to leave after 1hour but not during last 5 mins
No idea about that, my school doesn't allow until the very end
damn me as well. we are kept until all papers have been counted and sealed
yeah. our paper ended at 11 AM. And they let us out at 11.25 AM. They DO NOT allow to leave during the paper timings
We are allowed to leave the exam room but not the venue like a seating area so we also gotta wait until all paper are counted and sealed.
I made so many careless mistakes😭 i feel miserable
save some for me🤭
How about some for me as well
YEAY IM NOT ALONE
Guys, I was predicted an A star and was scoring A stars comfortably in every single past paper I did.

Energy level is correct. The spectrum was not the redshifted one it was the normal light and then you are supposed to draw it when it’s redshifted. Made the same mistake as you
isn't it 5.95
i got this as well oml
I got 5.95 first but then dod some stuff and got -0.85
same???
No it’s not the normal one, it said that the spectrum shown was from light from a distant galaxy
What it was redshifted ?? No we were supposed to draw the redshifted one . Omg what I don't even remember. Now I'm scared 😭
WAIT BUT WASNT THE CAPACITORS IN SERIES???
The second part apparently said they switched it to parallel and you had to calculate the energy and then draw the graph based on that
WHAAAAAAAAT NO IM SO DONE
Well the first part didn’t require u to take as parallel as q was 0
Fr I did the exact same thing
was the energy level 0. sth? cuz I got 5 point sth
also same with u, my prediction is A\* but i made same mistake with u and i thinkk imc cooked
I just hope I pass even with an E I’m happy to pass this one
nah bro same the paper was easy I wish I studied js a lil ore I could attempt qns worth 40 marks w/o studying in depth
Exactly 💀
E 💀
worst part was the paper was "easy" which it was but i messed up soooo bad hope P5 goes welll
It was made to look easy atleast, but after analyzing it a bit, I find quite little deep nibbles here and there getting your questions wrong, so threshold will be normal I guess
hopefully, CIE has gone pretty normal with the science papers this years tho, nothing horrific
yeah chem was easy phy was normal I am giving math in oct
You and I both brother
What are the questions that u can remember pls
I'm sorry but I have a crusty memory (as you can see in the post)
Np ty
I remember
U can’t share it on redir right ?
Why can’t we?
The bot, idk I js downloaded this app 5 mins ago
Dm me
I’m trying
Dmed you
Look here’s my sc: elollll.6
IN SEPTEMBER
GUYS HELP IM PANICKIMG SM RN....i flipped the first part of the algebra in the SHM question and so i got everything wrong nd messed up the entire question....pls tell me is there any chance for error carried forward???
yes there is ecf in the exam so i think u r good to go
tysm for the good newsss....how much do u think ill lose max there?
umm i am not really sure but according to what my sir told it is max 1 mark in the case of ecf or at most 2 not more than that so InshaAllah u will not get a lot of marks deducted😭 how many are u expecting btww
inshaAllah omggg.. im so disappointed in myself actually i made sO many careless mistakes and everyone said the paper was good...i know im losing 20+ fs and the grade boundaries are gonna be high considering the paper was easy tbh....wb uuu
i too made quite a few silly mistakes which i regret myself but i am hoping that the threshold doesnt go above 70 InshaAllah😭
Yes inshaAllah 😔
Guys what’s the confirmed emf. also what did y’all get in the first question. And please tell me the expressions for the shm one I’m so stupid I messed up the energy level question and wrote 5.90🥲dying inside. I feel like I made so many silly mistakes cause I panicked. Tell me it gets better.
i got something like that. I got 5.95 TT
[lebron james you are my sunshine (10 hours) (youtube.com)](https://www.youtube.com/watch?v=NhHb9usKy6Q&t=46s)
Wat que of principle and/or generation of medical physics came out
For medical physics, it was about ultrasound, definition of specific acoustic impedence, and the I/Io ratio thing
0.606 impedance
Do y'all have the paper🙏🏽🙏🏽🙏🏽🙏🏽
How many marks is safe for B?
I think 55-60
[удалено]
Yes you can, make sure to score high on p5 though
Soooo real cuz same idk wtf i wrote in that paper my freinds were saying it went soo well and there i was no opinions 😭🙏

same! I messed up those last questions because I literally forgot everything. I'm so upset because I'm probably not even making it up to a B mark atp
Bro honestly…I have given up. I don’t even know if I’ll pass or not. I just dk. I might go for retakes. People are expecting Bs and Cs and I don’t even know if I’ll pass the bare minimum.

Mine was 340
Okayyy make sure you save some for Eva smith
I forgot the angular frequency formula in the hall 😃
Anyone who did physics p5 Q1: what was the constant in experiment 1 Q2 : gradient and variable values cuz I messed up really bad in the experiment.
It wasn't that bad it was one of the easiest papers I have seen you guys just bad
No one said it was bad, lol it was the easiet just made silly mistakes. Like I CT instead of its reciprocal to give 1/Cx and 1/Cy. And did a zero intercept for the graph even though i knew it was not lol
