idk more like memorising specific frequent qs or like proofs or details and tricks said by the teacher is what rlly slips my mind
do you get the same kinds of questions again and again in an exam? or do they ask for particular proofs? if you KNOW thats going to happen why not just do more questions/proofs like that for revision so you get practise and you eventually wont need to memorise it? i think
@liamkk112 puts it better:
you shouldn’t need to cram the information of how to draw the graph, if you can follow the logical steps then there’s no need to do much memorisation and you can “derive” most of the results from things just making sense. additionally if you are applying formulas over and over again you will likely not forget them. so instead of memorising stuff like geometric series sum, do more geometric series questions and you’ll both memorise the formula and get better at geometric series.
and what they said about formulas still applies to frequent q's. for example, if you know that for extension 1 you will commonly get a multiple choice question asking to find the equation of a polynomial from a graph, try to understand how the graph relates to the equation (the zeroes of the equation are x-intercepts, constants of eq are y intercepts etc.) and then do a bunch of questions with graphs asking to find the equation.
also btw you don't need to write down certain reasoning things word for word. you can sort of paraphrase as long as its still correct.
if you truly need to rely on memorising question types and tricks thats an indication you don't understand the concept i reckon. or you just dont get enough revision and you tend to forget smth when you don't use/recall that info enough. it happens to me too, for example when i was revising for trials i realised some prelim content was completely erased from my mind, and that was my fault bc i wasn't revising properly.
this too, adhd and things like that can make it difficult to remember things. if it's truly not like an issue with your revision or whatever and the memory issues apply to all areas of your life you should get it checked out
