Hello,

follow NCERT. They have basic concepts and all theory question are asked directly from it.

for Physics , use RD sharma and HC verma. for Chemistry:- use OP Tondon for physical, organic and inorganic. it provides good amount of questions and material to read.

for preparation, solve previous year OJEE question. Book is easily available. you can get it online from WEB also.  You can also give mock tests to know how your performance is and where you have to work hard and where you have to study smartly.

if you find anything hard to remember them then draw them into figures. it will make easy for you to remember.

Hope it helps!
