CORRECTION: YOU WILL NOT SEE REPEAT QUESTIONS AMONG THE OG AND THE SUPPLEMENTS!!!

I found the supplement questions to be slightly easier and it had fewer questions compared with the original for the price. But the bottom line is that it contains official retired questions so it is a must have.

I didn't see any repeat questions on the Math supplement book and the OG11 either.

I have done both OG10, OG11 and verbal workout (not the math workout).

My impression was that many questions were familiar, which leads me think there were duplicate questions. Let me double check tonight.
