Dear Friend you may use NCERT books as base books and certain other renowned authors’ books as reference books, I may suggest some names here – H C Verma for Physics,.....O P Tondon for Chemistry and R D Sharma for Mathematics and along with that I would also opine that you may choose some leading institutions for admission as well, consider any one out of – College of Engineering, Trivandrum,,,,,,,,,,,,,Lovely Professional University, Phagwara,...........................BITS, Mesra,..........................BHU, Varanasi etc.
