Hey experts,

I have been told that the OG and OGVR questions are on the easier side and provide to only 30-40% preparation for someone looking to get a Q50.

What is the highest quality 3rd party question bank I should solve to get exposed to the high difficulty quant questions within the scope of GMAT?

KarishmaB BrentGMATPrepNow
Hello, studyprep282. I do not mean to step on any toes, so I would like to preface my post by saying that it will be interesting to see what Karishma and Brent have to say. I happen to be of a mind that OG/QR questions, well studied, are sufficient for someone aiming for a 50-51 in the section. If you feel the need to play it on the safe side, you can, of course, study more challenging materials. My recommendation would depend on where you are already scoring. Someone just starting out should probably focus on acing questions up through Medium difficulty rather than obsess over Hard ones. For someone sitting on a 47-48, I would recommend a different path. In alphabetical order, I would have you check out the following resources and select one that suits your needs and preferences:

1) GMAT Advanced—The Advanced problem set contains more challenging questions, as the title would suggest, and official questions categorized as Hard come at a premium.

2) GMAT Club Quant Tests and Quizzes—The question bank is deep, with over 1000 questions that cover all content areas. Bunuel is adept at crafting questions that test the sort of logic that is brought to bear on more challenging GMAT™ problems. A number of people have sung praises for this resource. (In full disclosure, I have access to this product for free, in exchange for some work I contributed to the site. I can vouch for the difficulty of the questions.)

3) Ian Stewart's quant books and problem sets—Like Bunuel, IanStewart is an Expert among Experts, and someone with his mathematics background and attention to detail knows just what he is talking about when it comes to creating GMAT™-like questions.

4) Manhattan Prep Advanced Quant—Probably the cheapest option. You get a couple hundred questions that are designed to be challenging. Some critics have said that the problems are too labor-intensive and non-GMAT™-like, but many people nevertheless leave positive reviews, and no one doubts that the Manhattan Prep team knows the material well.

5) Target Test Prep—Many debriefs mention how integral this online learning course was to their exam success. It is set up to be thorough and to build mastery, covering every type of question that may appear on the test, topic by topic.

That should be enough to get you started. Again, it will be interesting to see what Karishma and Brent have to say. (I have been singling both of them out for some time as Quant Experts I respect, as you can see for yourself, if you are curious.)

Good luck with your preparation.

- Andrew

Most test prep companies do a good job of making Quant questions. Use tags of 700+ to search questions of relevant topics on GMAT Club. You will get plenty to practice on and most of them will be within GMAT scope. Normally, the ones outside GMAT scope are tagged as such.
