If you're serious about the MBA and getting a top GMAT score, sign up without reservation.
I'm going to try to be succinct here as so many reviews are way too long. I am 100% confident I would not have been able to achieve my high GMAT score and acceptance into an M7 school without Manhattan Prep. Period. Their materials are great (both online and in print), the teacher I had was extremely helpful and they helped me with a proven method that takes the complexity out of this daunting process. If you put in the work (and that's half the bargain here) you will undoubtedly achieve better results with Manhattan Prep than working on your own. Yes, all these services are expensive but in the grand scheme of the costs of an MBA, it's a drop in the bucket. If you're serious about doing an MBA, make the investment. Worst thing I could say about my experience is that there was an administrative mix up one day and I got the wrong info about a class start time.... Not a big deal. These guys know what they're doing.
