It’s the first time I’m writing any long answer on quora, so please forgive my mistakes😅
1. 1st of all, analyse all the mistakes u did in 2021 exams and ur preparation phase and rectify them one by one, day by day
2. PYQs are most important, i.e., brahmastra. Attempt all PYQs from 2017-2021 at least 3 times. U can do also the papers before that but only after u have revised them 3 times, with proper tweaking of each and every question
3. Analyse last 3yrs marks vs rank and set a target accordingly, for nothing can be achieved without a specific target
4. In 2021, physics was unexpectedly tough and so doing HC VERMA only volume 2 is recommended
5. Don’t neglect inorganic chem, for its gonna be a rank decider. For rxns, I recommend u to go through the rxns of Grp 15 and 16(revise them every week for u have enough time), Chem bonding, Complex compounds
6. On a page, write all the organic chem rxns of every chapter in short, only initial and final products
7. Attempt adequately no of mocks from now itself from most relevant NTA ABHYAS rather than any Aakash or Allen for some questions come directly in real exam from NTA Abhyas mocks
