Excellent Value and Preparation

Magoosh was a fantastic choice for GMAT preparation. You need to be disciplined and persistent -- skills you'll need to enter any elite MBA program -- and follow through their well-structured study schedules.
The math videos are excellent and really give you a 360 degree view of the quantitative aspect of the GMAT. Many lessons are worth remembering for long after your GMAT.
Their weakest link was the verbal videos, which I found to be too theoretical and hard to follow. I suggest they take a lighter approach, but again, I had strong verbal scores prior to the examination.
Their practice bank is very good and seeing your progress as you solve 10-20 at a time definitely motivates you.
Magoosh also extended my subscription after I postponed my initial test date: a very generous gesture.
Great value for what you get out of it!
