I am planning to take a drop after class 12th to prepare for JEE, I stay in Lucknow, which will be the best coaching ? Options i am considering are 1) Gravity. 2) Allen 3) Akaash.

My first choice is Gravity, because my elder cousin, has studies the 2 years back, and he said teachers were great. Allen is new to lucknow, i dont know how is it? some of my friends said its good some said its not so good. They were not able to complete the syllabus before the first mains for dropper batch.
