I join FIITJEE in 2015-2016 for drop for advance preparation. I think that I am joining one of the best institute of india. But as I entered the class 1 st day I know that I do a wrong decision. Means I have lose more than 1 lakh rs. It is better to join a local coaching of IIT. Their faculy are totally dumb. They totally relax especially physics teacher. They dont care whether you pass or fail because they are getting a fix incone from FIITJEE . I only like chemistry teacher there. They act like that they got a govt job. If u want to enjoy your life then please go there. Full of ac, never seen buildings and walls all are there.
Only there study material and test papers are good( not too good comparison to resonance) but teachers cant solve there.
So its your decision to join or not because faculty us very bad.
