More GMAT Success Stories

 

One of the best parts about my job is hearing from students after they conquer the GMAT. I've gotten a couple of emails lately that I'd like to share with you.

First, from Alex H., who I've been working with for the last few weeks:

I just got back from the GMAT. I got a 750!

I wanted to say thank you for all of your help. The majority of my success on the test was due to our tutoring sessions. Thanks again.

Second, a customer discovered that Total GMAT Math is very well-suited to his studying style:

I especially like the fact that your guides are available by .pdf. Because they are .pdf, they are really easy to search for content . Also, I can print-out or work from the computer as needed, especially if my eyes are too tired from staring at computers all day at work.
