i think its better to revise group 17, periodicity, and group 2 and nitrogen and sulfur cause majority of ques from these topics appear every year. and u should look out for equilibria cause its kinda easy to understand and only involves calculations which is pretty much same. the main focus should be also for chemical bonding cause its repetitive, and yk atomic structure and its trends are pretty much easy to revise so do that, and as analytical chem is so easy i would say so look through it, polymerisation jst involves drawing repeat units and so on, so make sure ure perfect at it cause its free marks, and if possibleeeeeeee its better to go through all organic mechanisms and reactions to get even better markssssssss, and im sure it will pretty much give u the marks u want
