Hi all!

I recently took the GMAT and am concerned by my sub-80 percentile math score. I've been scoring consistently 47-48 in 4 takes of the GMAT Prep exams, so while I'd love to blame test day issues, my score is not exactly inconsistent with practice. For my retake, I'd love to score 50+ consistently so I'm not so dependent on verbal to pull up my overall score.

My question is: I've exhausted OG questions (both the

OG12 book and the quant specific book). I feel like I've gotten a good grasp of the stereotypically "hard problems" (e.g. combinatorics) and timing, but it tends to be those subtle basics that I have the hardest time with (e.g. tricky number properties questions).

I've read through the forum and I'm considering either MGMAT (both exams and their prep books) or Jeff Sackmann's Total GMAT Hacks (I'm a big fan of the way he explains OG problems on his website).

For those who have similarly exhausted OG problems and are looking to push their Q score to a similar level, what books and official exams do you recommend?

Any advice would be greatly greatly appreciated. I know there's a lot of similar threads floating, but I haven't found one that quite hits the nail on the head.

If you are aiming for Q50, I would suggest you to take a look at my blog. I like to tackle the more advanced topics in that and I also like to discuss alternative time saving methods. These things become critical at such high scores.
