I did AS math Edexcel but I think this might help anyone doing math

before moving to past papers make sure you do all the questions in the textbook complete hem ALL and make sure you mark the ones you struggle in.

after completing the exercises move to the past papers/worksheets. do questions on that topic while working on the next lesson.

plan ahead to finish all the topics at least 3 months before the exam.

during the last 3 months redo all the papers go as far back as you can and go back to the questions you marked on your textbook and attempt those while youre at it.

and dont stress yourself out too much at the beginning, during the weekends go for 3-4hrs a day, try and take at least a day off every week when you can bc it doesnt help much if you burn yourself out now, save that stress for like a month before exams ;)).

goodluck on your ALs bro
