Good but not great

I found the Manhattan GMAT resources to be extremely useful throughout the study process. Their syllabus, combined with MGMAT handing you all of the resources you needed, made the potentially overwhelming process of studying feel more manageable.

I didn't love the class, though. My instructor was Marcus and though he was clearly smart and and a decent teacher, I found his jokes to be distracting and take up too much time. It sometimes seemed as though he was jumping all over the place in terms of content. It was probably the most useful in terms of familiarizing me with the content.

In the end, I found studying on my own to be the most useful. Taking practice tests and going over exam questions taught me a lot more than the class or other studying. My first practice test was a 630, and my actual GMAT was a 730 (68% quant, 99% verbal).
