I had the pleasure of having Stuart Park as my instructor for my GMAT prep course and he exceeded my expectations. I knew this was going to be an online course, but I did not expect to have such great communication and feedback from Stuart. Any time a question was asked, he would break down the logic of our thinking to determine why we thought what we thought and he would explain the correct answer, explain how he thinks we got to our answer (most of the time he was correct), then he would tell us the fallacy in our thinking. But he somehow did it so that you could learn on your own without just having to give you the answer. I would highly recommend Stuart Park, and I plan on retaking the course. It was a pleasure! read more
