Recommend Manhattan Prep GMAT

I took the 9 week course with Gregg Lachow. He was an excellent instructor. I found that the class moved at a good clip which I really appreciated since I was aiming for a high score. He was very clear in his explanations and as good at responding to all types of questions. I found him to be equally adept at verbal and quant. He has a passion / gift for teaching and a great attitude. He is also pretty funny which helps due to the boring nature of the topic.

In some ways, the course is really what you make of it. I sort of stopped doing the homework halfway through and I didn't get nearly as much benefit (no surprise there). So I strongly recommend doing all the recommended and required homework. I still really was able to master the fundamentals and techniques. The Manhattan Prep method is excellent as are their materials.

Since I didn't do all of the homework I ended up doing a lot of self study with the official guide which I also recommend. I also took advantage of many of the online resources.

Ultimately I scored well and I think it was in large part thanks to Gregg's class.
