It's so haphazardly put together I'm sure the real GMAT is nothing like this... It's very unlikely that this software emulates the adaptive GMAT format. Also, it's got tons of math mistakes in its design.
I just had to come on to help anyone who was thinking of actually paying for this software... DON'T!!! It's a total scam. Out of the 5 problems it lets you on the free version, I ran into 2 mistakes in the design of the test!!! Things like:
1) it accidentally subtracted 4 from 7 instead 3...
2) it thought that 230.7 / 0.7 = 12.83 (What?!?!)
it's ridiculous... a very frustrating and stupid piece of software. They should pay you to use it.
