Help regarding JEE !

I am currently in Class 10th and planning to prepare for JEE in Class 11th and 12th . I intend to enroll in the PW online batch for my JEE preparation. I am looking for a regular school with a few dummy students or a fully dummy school that would suit my needs. I am searching for such a school early because my current school has set a specific deadline after which no student will be allowed to leave.

Please guide me and suggest suitable schools.
