Hello Aspirant,

I would like to tell you that Arihant Books are very good for JEE preparation and for other competitive exams as well. Its an awesome resource for quality problems and must have for self-study students who are serious . It will help you clear all the concepts which are taught in coaching. Coaching guys can use it as extra practice. This is must solve for self-study guys if you wanna crack JEE(Advanced).

Arihant books are always good for preparing for jee advance but level of this books are quite tough. So I recommend you to clear all your basic concepts from Ncert book first and then go for Arihant.

Further, I would suggest you to follow the mentioned link to know more about the  best books for preparation in JEE mains and JEE advanced :
