If you are preparing for NEET 2021 and also side by side thinking about NEET 2022 then I guess u are currently studying in class 12th…
Tell me one thing why are you already thinking of taking a drop you still have 6 months left, you don’t have to go to school for some more days I guess, you are like a dummy student so take the advantage of circumstances… I know it is easy to advise and staying all the time at home and studying is very boring and monotonous many times but believe I did the same mistake, I wasted a lot of time in this lockdown and now my regret and frustration has no boundaries…. If you excel after these 6 months your happiness would see no bounds because from my personal experience I can assure you that the journey of drop year is not at all easy it comes with tremendous pressure and many breakdowns.
As far as prepration strategy is concerned I will only say one thing NCERT just stick to it even in physics and physical chemistry…. Observing the lastest trend of exam paper will be solely based on NCERT there is no need to go too high… Yes you can surely go a bit high as keeping a save side is always good..
