Dear Student, you may visit a few renowned institutions and request them for demo classes and get an impression which one is better,  Additionally you can also make efforts on your own for self practice at home, you may get notes from askiitians link, use NCERT books as a base, consult renowned authors’ publications for reference books like for Physics –  H C Verma, For Chemistry –O P Tondon and for Mathematics – R D Sharma. Along with it keep an eye on leading institutions where you may get assured placements and quality education too, like – CMR College of Engineering, Hyderabad,.................Lovely Professional University, Phagwara,..................Ambalika Institute of Management and Technology,Lucknow etc.
