Best value out there

Loved the course. Went from 590 to 710(Q47 V41). 4 months of prep in between attempts. I finished the course by watching all the videos, answering all the questions, and watching all the videos on missed questions. I sent two emails to customer services while I had the subscription and they responded within 24 hours. This course along with the OG and manhattan prep books is all you need to be very successful on the GMAT. I know if I spent some more time with these 3 resources I could boost by score even higher. The score guarantee provided the assurance I was looking for (even though I improved by 120 points!). The "resources" tab in the program was also extremely helpful. The blog has a great many articles about test taking skills (I think these are available without the subscription as well).

This program should be your first move for GMAT prep. If it doesn't work out you can always pay $1,500 for a high end course. You can download apps on your phone for flashcards and videos, which allowed me to study during lunch breaks at work. Thanks to Mike McGarry and the Magoosh team.
