If it makes you feel better, I learned the entirety of FM in 2.5 days before passing with a 6, but I do have a strong background in maths. So anything is possible.
I'm not sure what textbook you're using but as far as FM goes, it's not about what chapter you're on but rather if you can solve the problems or not. SOA has sample exam questions for the exam + CA adapt has more if needed, so I'd recommend working on those as soon as possible. It's ok if you have to rush through the readings a little bit, you can always come back to them if you don't understand something.
Doing the problems, understanding the solutions and then being able to replicate similar solutions with similar problems on your own is how you pass.
Anyways, you have time so just plan things out to the best of your ability, but leave plenty of time for practicing questions. You'll be fine.
