From 540 to 710

In my opinion, this is a must-have for anyone studying for the GMAT. I used a combination of tools but I credit Magoosh with much of my progress because of the detailed, easy-to-follow explanations and the ease of use. There are a lot of services that offer practice questions but Magoosh helped me clearly understand what I was doing wrong and taught me strategies for how to work faster and smarter. Also, the ability to customize practice sessions by category and difficulty level was incredibly helpful when I needed to zero in on problem areas. It's really easy to log-in even for a quick 15 minutes when you have it - every minute counts.
