The test gets more difficult each month. I took it in August and at that time, Gprep was very close to the real test.
RC's are shorter, but the questions are more difficult.
CRs are a lot tougher.
SCs are about the same.
Math is way more difficult.
I had no problem with verbal, and scored in the 97th % without ever studying for it, so I'm afriad to try and mess myself up by doing anything with that.
The math I struggled with beyond belief. You can read my post test report from way back, but basically I got a kaplan
tutor, went through all their stuff, did the OG as well as the Princeton guide, but still did terrible on the math section.
What is more difficult about it now? My weakest area was geometry, but I also had a lot of trouble with the more advanced DS questions of every type.
