Yes you can take the coaching but I guess you should 1st focus on you r10th boards and then think about coaching when you are in your 11th grade.

You can take coaching from FIITJEE in Delhi iyys famous for IIT.

Actually, FIITJEE is better than Resonance for IIT-JEE Mains+Advanced coaching. FIITJEE is good in terms of practice papers, daily tests, doubts clarification, detail explanation, grand tests, etc.

Study materials of all coaching institutions will be more or less similar. It depends upon how you study. However, according to my personal opinion, you should take Allen DLP course.

Hello Manik,
It's great to know your thought process. There are hundreds of students who get admission in IIT without any coaching for coaching institutes.
Best wishes.
