Great product - lots of hard work

Bought its premium which involves both verbal and quant. Had a initial score of 620 (not great) and was able to improve it to 660 in a month or so.

They run you through a TON of exercises to and track your progressive scores. Clear and easy to follow interface and can actually see your progress throughout the tests that you do. You dont have to sit through a test every time and can actually just do them whenever you have time and will save your progress. Its nice to see a predictive GMAT score as you go through the test one by one as well.

Only cons I see is more the support and phone application when I was using it. The interface to complete on the phone was clunky and didnt really sync properly to your account.
