hi,

see state board books of wbhse is standard , however you need to have grip over english and need to understand the terms, often students get confused of questions when ever attempting in english version papers, however it would be best if you follow arihant mcq books for practicing the questions, and also follow the previous years papers.

careers360 has jee main knockout program for students who are going to attempt jee main april session, you may join the program to boost your performances,

Hello student I believe state board books are not enough for Jee, prefer NCERT to build your basic concept and make sure you do each and every example and exercise questions of Ncert before jumping to a reference book after completing ncert thoroughly refer to your coaching material or any reference book as mentioned below -

Concept of physics by HC VERMA

JDLEE chemistry

OP TONDON CHEMISTRY

Arihant practice book for Jee main.
