I studied Biology from Dr.Sailesh Jaiswal Sir who is a very good teacher with an excellent way of teaching which mainly aims to give depth knowledge required for NEET and also insists to clear concepts, His video lecture and notes are excellent which covers whole NCERT and also some topics outside the NCERT required for attempting question coming out of NCERT in NEET Exam.i highly recommend his biology classes to every NEET Aspirants.
