This institute provides really nice educational faculties.You would love studying with teachers here, as while teaching they also make you laugh badly. VMC is considered as a family hence you are call your gurus(teachers) Bhaiyyas. They make IIT JEE studying package really simple! Now I think NCERT is tougher than the rest(maybe because my school teachers are ridiculous in teaching).
However Institute does not provide any regular classes, you can have class anytime, any day according to their wishes. Also your doubts are delayed till 4th class of that particular subject(which happens after a month or so). Neglecting its demerits and keeping in mind that every coaching institute has some weakness or the other, I highly recommend you to join VMC.
