Hey guyz,

I'm planning to buy the supplements (math & verbal) of OG-12 (2nd edition) books. But before that, just want to enquire with you whether the questions are repetitive from OG 12/OG 11/any previous edition supplements or not. I heard that just like OG 12 review, most of the questions will be repetitive in supplements as well from previous editions. But want to hear opinions from people who have already used this before. If it is repetitive, then its a sheer waste of money to buy these.

The 2nd edition reviews contain only about a third new questions as compared to the 1st edition. They do not overlap with the official guides.

All,

Thanks for your inputs! I have a basic doubt reg OG books. Now, we have main review book and supplements. Does the questions in supplements get repeated from main review book?

If No, then does the questions in OG supplements 2nd edition get repeated from its previous edition's supplements?

No, the supplements are entirely separate and won't overlap with the OG.

About 2/3 of the questions from the second edition supplements are repeats from the first edition.
