Hi Rajnish,

If you are talking about JEE preparation coaching, you have along road to go now. First of all, concentrate on all NCERT books to clear your fundamentals. NCERT books are very important for basic concept. After that, you may consider practicing from your coaching modules. But, be sure to take advice from seniors of the coaching to know if the modules are worth it. I have studied with Vidyamandir and FIITJEE modules. VMC modules are too long and not always helpful whereas FIITJEE modules lose their context after a few questions. So, first know about your modules. In addition to that, you can refer to the all time favourite books for IITians which include Physics by HC Verma, DC Pandey, Trigonometry basics by Arihant. However, clearing your concepts is the first and foremost step and do not jump onto heavy books before completing your NCERTs.

Wish you all the best.
