Thoughts?

The PowerPrep exams shouldn't be more difficult. In fact, PowerPrep (to be clear: not GMATPrep) draws its questions from OG10.

Do you feel anxiety when you go through practice tests? It's one thing to be practicing GMAT questions from a textbook at your own pace; it's an altogether different experience when you attempt to answer GMAT questions in an actual test environment.

Best of luck!
