IIT preparatory course is better or Allen coaching will be better

To best of my knowledge IIT Ptreparatory course will be better than anywhere else, the simple reason is that they will most probably be very close to the type of questions which are going to be offered in the test and the othre academies or coaching centers may be veryb promising but may not be up to the mark, rest all is up to you to decide as you are the one who ios at the receiving end. But I may certainly be sure to guide you regarding some reputed institutions like – Anna University, Chennai.............................SASTRA University, Thanjavur,..............................JJTU, jhunjhunu,..................Lovely Professional University, Phagwara
