Good for the 600-700 Range or 700+ with extra effort

The MGMAT recorded courses are great if you want to score between 600-700, which may be all you need. However, in order to get 700+ the courses themselves don't really cut it.

On the other hand, the books, online tests, and other materials are GREAT! Paired with Google it's all you need to drag you up from a 500 to a 770 ;)

The yellow pad and pen are a great addition to the pack - it eases you into the simulating the tests. The online tests the MGMAT has are a bit more challenging in the math department than the real test but the pressure that creates to learn the shortcuts of the math problems will help you out. SC was what tripped me up the most, but the MGMAT SC book paired with the Official Guide (included in the package) dragged me through that kicking and screaming.

And of course, since it is a pricey course, after you're all done you can sell the books on ebay for a few hundred too. If I were to do it again I'd skip the 9 online courses and just get all the books + online practice exams.
