Hi,
Although the math questions of the
OG 12th seem easy to me, my current level in math is 45. My explanation is that the
OG 12th doesn't cover the diverse math topics deeply. So when I take the GMAT Prep, there are some type of problems that I have not seen in the OG.
In this sense, I have read that Jeff Sackmann's
Total GMAT Math could be very helpful. Even I have read a review, I think that it was written by bb, in which it mentions that it is a excellent book to get a 50 in quant. For example, it has 100 questions whose level is 700+.
However, I have read that Jeff Sackmann's Math Sets could be better because there are more questions (1000) and maybe more difficult. The problem is that the sets cost USD 250, and I don't know if it is necessary to study 1000 questions!
What do you think? As additional information, I must say that I master most of the concepts of quant; also, I have the
MGMAT guides, and I have access to the GMAT Club math tests.
Thank you very much!
PS. Are the Sackmann's Sets divided by difficulty level? Really, I don't want to spend hours and hours in sub 600 level questions. I want 650 level questions, and then 700+ level questions.
