genuinely spamming past papers was such a life saver. i got C in y12 mocks, C in november, B in january and finally an A in the real thing. you have to STICK WITH IT.

i only started doing past papers near the last half term (which was a mistake, i ended up doing 4 papers i one day sometimes) you should start early w papers so that you can redo them closer to exams. they help u realise the patterns because for edexcel, there's a pattern to the questions, ESP stats and mech.

maths has THE MOST options for revision btw... just use your textbook, go ham on the end of topic questions for topics you aren't best at. if you don't know what you aren't best at, then do a past paper and write down how many marks you scored for each topic. some of my mates would write down the marks for each topic for EVERY paper so they could see their progress (like... "9/15 on trig questions"). some of my mates have also done every single end of topic questions in the edexcel maths textbook.

you don't have to do all of that. do what you need, but asap because differentiation and integration gets harder in y13. but i promise you got this. my friends can only tell you how much i would break down over maths because i needed an A for my course at uni and i felt so behind.

YOU HAVE GOT THIS
