Not a good choice at 10+2 level if you are planning to join it for neet preparations. The coaching is not so cbse- neet oriented( need of the hour) . I had joined it in 12th grade and was highly disappointed as there was a lack of faculty and even the syllabus was not completed on time. But for droppers it is a good Institute to join. SKD sir, the founder, is a really famous Physics teacher and he really is great. After Aakash Institute in Lucknow SKD is the only best choice left.
So it’s recommended to join it if you are dropping this year.
