After about 1,5 month of thorough studying (Manhattan booklets,
OG's) I took the GMAT. Real bummer, I scored a 530 (needed at least a 600). It was obvious that my approach wasn't effective at all, so I began to look for other online prep companies. I came across EMPOWERgmat. What I liked at first is that you can try it out for 24 hours and after that you pay a monthly fee of $99,- and that's it - you get acces to all the content and you can choose your x month study plan. I only had about a month so I chose the 1 month study plan. The content is simply great. EMPOWERgmat got the GMAT all figured out and knows exactly how it works. They arranged the topics in such order that you're optimally prepared upon test day. They have mini clinic videos - explaining the best techniques and tactics for a particular subject. Furthermore they back-up every question with a short, but powerful explanation video. For me it was almost fun, preparing for the GMAT this way, since I knew that everything I was doing, was the right thing at the right time. The support team is awesome as well. Whenever you have a question they almost immediately reply.
In my month of preparation with EMPOWERgmat I only got to finish about 40% of the content, but still got up 110 points - I mean that's just amazing. I firmly believe that if one completes all the content from EMPOWERgmat (preferably in a 3 month study plan - this gives you a life besides the GMAT), the 700 is an easy target.
I would recommend everyone to go with EMPOWERgmat, they are great!
