GRAViitY is an institute run by iitians, where they provide complete trainings & coaching majorly for IITJEE, AIEEE & WBJEE & OTHER EXAMS like SAT, NTSE, OLYMPIADS, KVYP, ISI. I feel no institiute in kolkata can claim the education quality they are providing..... I suggest all the students aiming for professional career in engineering should approach "GRAViitY " first..
