What People Are Saying:

“Brett’s videos and worksheets made the concepts significantly more understandable than the name-brand textbooks I was trying to use on my own. It’s truly amazing to see how the quantitative problems on the GMAT can be methodically dissected and attacked with a strategic game-plan. Brett is a talented and passionate instructor who always seemed to go the extra mile, and I feel lucky to have come across his video tutorials. Dominate the GMAT was nothing short of an excellent experience.”
