Hii Rahul,

Actually its upon you,by which study material you can understand the concepts crystal clearly.

As per my experience in Kota the best basic clearing study material is of Resonance.For question(tough) practicing the best material is of FIITJEE .Motion study material is also good as it have lots of question to practice . Akash material I would not recommend as they have repeated the same type of question again and again.

Apart from study materials always solve previous year question paper of last 15 years because 30% question are repeated.

Hope this will help you. Please feel free to ask if you have any further queries.

Thank You.
