Thanks!

There should be no overlap between questions you see in OG and the questions you see on the actual GMAT. It is quite possible, however, that you will see questions that are very similar to OG on the actual GMAT, but they will never be the same. I found this to be the case when I took the GMAT.
This is true for both the math and verbal sections. Have you heard otherwise for the math section?
