Total GMAT Math: 760 Success Story


Since I released Total GMAT Math a few weeks ago, I've e-shipped dozens of copies, gotten some great feedback, and polished some of the rough edges.

The most gratifying part of my job is hearing from people who have reached their goals. Brandon H. wrote me this morning to report on his impressive success:

I wanted to drop you a line to personally thank you for the help your Total GMAT Math gave me on my recent test. As I began studying for the test, I wrongly assumed that the quant section would be a breeze considering my background (financial analysis). My first practice test quickly doused those thoughts, as I scored a 40 quant. Over the next month or so, I diligently studied the Official Guide and Princeton Review's Math Review.

Feeling more confident, I took another practice exam and scored a 38 on the quant. Subsequent tests were only marginally better...41, 43, etc. At that point (about a month ago), I officially freaked out. I ordered Total GMAT Math that day and spent the next several weeks pouring over it. The punchline to all of this came this past Saturday, when I took the GMAT, and scored a 760 (V: 46 Q: 49). I can say without qualification that I NEVER would have pulled out a 49 quant score without your product.

Having used virtually every study material available (OG, Princeton, Kaplan), Total GMAT Math is far and away the best study material available. Princeton Review's Math Review is junk in comparison. It was the best $50 I've ever spent.

Congratulations, and thank you, Brandon. You obviously worked very hard to reach that goal, and I'm glad I was able to help.

Many of you who have purchased Total GMAT Math are undoubtedly still preparing for the test. When the big day finally arrives, be sure to drop me a line and let me know how you did!
