my aim is to seat in NIT warangal in computer science so how much should I get in percentile or marks in JEE main so that I could achieve my aim?? and also please suggest me a strategy at this moment so that I can achieve my dream??

Hello, Nit Warangal comes under top Nit of India being placement wise or infrastructure wise and getting CS here is also a diffult task as cutoffs are very high.

So, a exact prediction of score or rank is very diffult as cutoffs changes every year.

But you should aim for minimum 5000 rank and marks above 250 to get a good chance.

And for preparation read ncert line by line solve Ncert exercise questions especially for chemistry.
Learn inoraganic chemistry by remembering exception and other facts.

Learn organic chemistry reactions and their mechanism.

Solve H.C. Verma and D.C Pandey book for Physics.
For maths solve from questions from class 12 part and chapters important are 3D, Vector ,calculus, complex Number ,binomial theorem, circle,parabola, hyperbola, ellipse, probability.

Make short notes and formulas.
Give mock test.

This should help you and most importantly solve all previous years questions of Jee mains and advance.
