MGMAT Online - Great Instructors

I highly recommend Manhattan GMAT on-line course. It is live and taught by the teachers who scored in the 99th percentile. In addition, MGMAT puts all of the instructors through a 100-hour training program, so they definitely come prepared for the course. I took the on-line course with MGMAT in winter, and I must say that I was very impressed with the quality of the material offered and the instructors (we had 2). The good thing about the on-line course is that you can take in while at home in your bed :) and you can ask questions live (they provide the headphones with microphone). The class is highly interactive, so you will not be bored at all.
I am not affiliated in any way with MGMAT. I'm just a big fan of their teaching model and the quality of the materials. If you are interested, I've dug out a free virtual preview class posting on their web-site. The event is happening tomorrow, so you can sign up for the preview of their on-line class today and see what their program is all about tomorrow :) .
