Sure.
Pros:
1) Both the Verbal and Quant parts are very good and teach the basics concepts and the more advanced ones. To accomplish the goal to become a Gmat assassin, Rich and Max use mini lessons and a lot of different sample exercises, with the explanations. I think that their teaching method is very effective.
2) The Quant Part, RC and CR are awesome. There are a lot of very very very effective tricks that they taught me.
3) Simple and effective interface.
4) Cheap when compared to other Gmat courses. I have decided to purchase just a month for 99 bucks and then another one for 99 (because I had the exam on the 15th of March and the first month had expired on March 1st). There is also the possibility to choose a 3 month pack with several Gmat Prep exams and I think I would have chosen that one if I had had more time (deadlines...).
5) It is not only a platform of learning but also a platform of advice. Max and Rich will tell you how to approach the exam not just with the theorical concepts but also with useful anecdotes.
6) Max and Rich were ready to answer (via email) any doubt I had on the exercises.
Cons:
1) SC is not at the same level as the other sections. It is very good, but the others are a step beyond.
2) Even though there are a lot of exercises, I felt that there should have been even more. That's why I think that the
OG is still necessary to exercise to achieve a good score.
3) The videos stopped from time to time and I had to refresh the page (but I think it was just a problem of my PC).
