Hello there ,

Hope you are doing well m See,you can't determine the exact marks that you are going to get in NEET-2022 by solving certain specific books . Scoring 650 depends on a lot of other factors as well like your exam temperament . But mainly it's your hardwork and confidence that will pave your way to your goal . I'll list few points below .Act accordingly and you are surely going to do well.

Stick to NCERTs whatsoever!(I can't stress this enough) ,specially for biology ,organic and inorganic chemistry. There's no need to do theory from anywhere else for these subjects/topics .

Practice ample no. of questions from standard practice books like MTG . Then revise it multiple times . Don't switch sources without completing the earlier .

Read and revise biology NCERT word to word and practice all diagrams ,flowcharts and tables as many times as you can .

Give ample no. of mock tests of standard coaching institutes in a time bound manner and make a mistake book in which you'll write all your mistakes while analysing the paper .

Also,do solve the past 15 years papers of NEET and past 5 years papers of JEE Mains to have a better idea of the kind of questions that are actually asked in the exam .

Don't get distracted ! For this time ,get rid of all your distraction .

Know about your body clock and have a proper sleep-wake cycle . Your health is of prime importance during the preparation. Also have proper and healthy meals regularly.

You can also join some online or offline classes for learning and strengthening concepts and topics .But always give your self-study the prime importance.

These are the main pointers that you should keep in mind . This should help you in cracking NEET, whichever year you are giving ,with flying colours .

All the best!

Hope my answer helped .
