I beg to differ on the above comment......I have studied at Princeton Review
, Bali Nagar branch and scored 690 on my GMAT.
Even though I joined GMAT batch for the preparation, I was given 1 on 1 doubt sessions after the completion of course at the center. Trainers allotted to us were Sapna and Ashish and both of them never said no for any kind of doubt session or any extra help session. I believe its not a good idea to put the blame on faculty members because of your deficiencies. As far as the fees is concerned, you could have contacted the HO or the center head for the clarification.
I used the study material of Princeton Review
and also did 10thOG as well as 13thOG which proved to be sufficient. Also the tests were helpful in gauging my performance from time to time.
I would recommend everyone to visit the center and meet the trainers personally and then decide rather than following any post online as they are generally biased.
