Can anyone share any experience with Manhattan Review - GMAT Weekend Classroom Crash Course. I am considering taking it up if it can help me with increasing my score from 620 to 720 and above. I hope this to be my last attempt since my previous two attempts got me 600 and most recently 620. Since the course is expensive, I want to be dead sure that this really assists me in increasing my score to beyond 700. I have never taken any classroom prep course before so this is just one last ditch desparate attempt at trying out everything that can possibly help me achieve my objective of scoring 720 and above. I would consider my GMAT fundamentals to be reasonably good having prepared twice for close to 3 months each time.
Kindly advise. I would like to hear the experiences from those who have either attended the course themselves or received feedback from friends who have attended the weekend course.
