Hi
I joined Jamboree in NFC for GMAT and found it absolutely rubbish.
TM and online resources are much better resources.

Can someone make any comments regarding these institutes (IMS, Jamboree) etc for preparation of applications and interview ?

Also, is it better to join these insti's or buy books like Richard Montauk
and the likes ?

(Also PM me if someone interested in sharing app books)
