Really helps with Verbal

Lots of practice material. Fairly good tutors. What I particularly liked was that you could set up an appointment with a tutor to master a particular topic ahead of time. This improved my confidence and gave me extra time to practice.

The quant course could use a little improvement though as there is a lesser focus on maintaining the timing required by GMAT. It does get you past the basics, though.

The essay section was given minimal focus. It's something they expect you to prepare on your own. Not recommended if you struggle at writing essays.

The Integrated Reasoning section was well taught. It also has increased importance if you claim to come from a quantitative background.
