I studied two years at fiitjee delhi .
south delhi centre.
only thing I can say using my experience is
if you want to make ur concepts original come here
I mean if u want to be really strong at concepts
anD HOW TO SOLVE a Unknown question
how to handle with it
they will teach u to the best
only thing required is u need to be dedicated
dedication is required forany field
give them ur dedication. they will make u crack
any type of question in competitive exam now a days
FIITJEE is very goood choice specially for those
who want to get a rank < 100 . they are good at it
they will also teach what NOT TO DO to avoid distraction in
studies.
ok thats it. go and get enrolled there. work really hard
u will get ur dream college.
