Hey Divyesh if you mean you wanna prepare for NEET UG and want tips to score more than 450 this year, i will help you out,

BIOLOGY- easiest part, read NCERT cover to cover , page by page, every line must be memorised, even the tables, and solve as many questions as you can , around 300/360 is only from NCERT, so aim atleast 300 plus in bio, and you just need another 150 in phy and che

PHY and CHE- the important part here is understanding the concepts really well, clarify any doubts you have and the crucial part is solving questions, solve as many as you can 200 plus in every chapter, verify,rectify ,analyse and solve again, you will nail it, good luck
