Math Questions on OG11..sufficient?

[ssy]

Several posters on this forum have mentiond that the math questions on the OG 11 guide are easier than what we would normally see on the actual GMAT test. Is this true even with regards to the last 50 or so questions in each math section of the guide? If so, what else should we practice with?

I'm currently only practicing and reviewing the last 50-80 questions on each section of the OG guide which I believe are the harder questions..would this be sufficient? I'm aiming for a math score in the mid-40s range so I do not expect to see the absolute hardest questions on the test.

Thanks for your advice.

Can you buy Quant supplement? If yes, please do that along with OG11.

My advice would be, do not stick to those last few questions. The idea is not doing or understanding the concepts mentioned in last 50 questions in OG11. The main idea is practice the forulae and concepts again and again.

My study plan included OG11, Quant supplement and Kaplan-800.
