Hello Swastika,

I admire your choice of preoparing for NEET. First I'll suggest you to read NCERT textbooks thoroughly, they are your Holy books now onwards. For reference purpose i personally suggest MTG books. Bur Arihant, GRB, and others publications are also good.

Strategies for preparation is Concentrate, Focus, Practice, Remember, And Repeat. That will really make sure your good rank. But be healthy and happy first, then only you can concentrate. For Biology you need more Logic and Memory power, for Chemistry you need more Concentration and For Physics you need to be Fast in Calculations. But for all the three you need to have better Understanding capability.

Hope this helped you much. Be free to ask more, we are here to help you.

All the best for your bright future. Thank you.
