I was looking at some of the in-person classes that are being offered in Silicon Valley this summer. Can you please give some feedback if you have taken one of these courses? Also, I was wondering how this course is structured i.e. does it focus more on doing tests or does it cover some fundamentals too (esp. in Math since my math skills are just about average). Also, I am sure MGMAT has quite a few really good instructors but was just wondering if there is anyone specific who is recommended. Thanks a lot.
