Hello,

According to the new rule that has been released by the government, student under the age of 16 cannot be admitted to coaching institutes and as you are still in class 10th, I would recommend you to first focus on your studies and give your board exams as they matter a lot. Your academics must be strong, you can start self study for IIT JEE Mains right now and in 11th or 12, you can go for the coachings. Top institutes in Delhi for your preparation are:

1) Allen

2) FIITJEE

3) Aakash Institute

4) Physics Wallah

5) T.I.M.E

Hope this helps you,

All the best
