GMAT Math

Is there any place where I can find the explanations of the Gmat prep software questions?

I did my first test after two weeks studying, and I get a 610 (45 quant and I don't remember verb, 32 aprox), am I a lot far from a score of 700 in a real exam? (I've been told that gmat prep software is easier than the real test)

It is much harder than the testprep. But, ussually is the best prediction for the test. At the 600 level is going to be very challenging to break it. You can do it!
