HI Aspirant!

Yes definitely, coaching centres also teach NCERT books as the NCERT books of 9th to 12th class plays a vital role in the prelims round of UPSC exam. With NCERT books they also cover the standard books as these books have more question content and are written from the ground up. They form the foundation of your knowledge. Coaching centres also provide their coaching notes, they are helpful in revision before the exam.

Thankyou!
