best way to revise a level chem ?

okayyyy , so i finished the whole aqa a level chem spec n *basically* started my revision .. i’m js wondering ,, what’s the best way to revise ? esp for chem . like all i’m doing rn is topic qs from pmt / studymind n going thru my tb or yt vids when i’m stuck . idk if this is rly like helping me or is effective , but ik most ppl say to js do past papers . i’ve only js revised the atomic structure topic so i’m curious is this effective n useful enough for the rest of the chem subj ? any n every advice is appreciatedddd

Defo continue with exam questions, note down the questions/topic you got wrong and look at the mark scheme and use that to help you revise. if your still not understanding that topic/ getting those questions right go on youtube watch a vid make notes on a whiteboard/ paper then pause the vid rewrite what youve learnt without looking back. then correct or add any extra info you forgot. then go back to the exam questions and reatempt them, i find this the best way to revise.
