Magoosh’s very own Mike McGarry, GMAT/Math Teacher/Tutor/Foosball player extraordinaire, went through 5 different sets of Official GMAT Practice Material and tallied questions based on the subject material they tested to find the most common GMAT questions.

Here are the samples of Official Material he used to figure out the GMAT Quant breakdown:

1.GMAT Official Guide (12th Edition) Problem Solving Practice Questions (Pg. 152-265)*

2. GMAT Official Guide (12th Edition) Data Sufficiency Practice Questions (Pg. 272-351)*

3. GMATPrep Test #1

4. GMATPrep Test #2

5. Released past exam from GMAC, test code 14, from the 90s/early 2000’s

**Side note: we have video explanations for all of the practice questions in the Official Guide here.*

*The categories*

The list of concepts tested on the quantitative section is from GMAC, which you can see on page 107 of the Official Guide (either 12th or 13th edition). It isn’t perfect– “Integer Properties” is a wide area of knowledge, whereas something like “Circles” is very specific.

*Observations*

- Based on the master chart alone, Arithmetic is the clear “winner”, while Word Problems and most Geometry question are ranked much lower.
- Though the rankings vary slightly from chart to chart, there are no extreme outliers in terms of the sets of data– even the old released exam is quite consistent with all of the other exams.

*“Well, I guess I’ll just throw parallel/perpendicular lines out the window, then”*

NO. For the sake of simplicity and accuracy in reporting absolute frequency, we’ve only assigned each question to one concept. This means that even though GMAC lists “Perpendicular lines” as a topic tested on the GMAT, and we have 0 questions marked as pertaining to that topic, that certainly doesn’t mean the idea of perpendicular lines did not come up at all on all of the exams. It certainly appeared, but often in questions that were better categorized, overall, as “Coordinate Geometry”, or “Intersecting Angles and Lines”.

*Takeaways*

We hope this serves as a guideline for the relative frequency of math topics tested on the GMAT to help you decide how to focus your time! In Magoosh practice, you can set up customized practice sessions to focus on specific concepts, as well as review your performance on individual concepts to identify your weak spots using our Review tool.

Let us know whether you find this type of breakdown helpful, and whether you have any questions about any of the information above! 🙂

This is great!

This distribution is a little bit dated.

Has anyone done similar exercise more recently, especially considering that importance of Integrated Reasoning has increased (so some topics will get tested there, and so may not get so much focus in Quant)?

This is an interesting question, Sumedh! I’ve passed this along to our content team to look into. Some of these resources, like the GMATPrep tests, are still relevant, and you should be able to regard this as a good benchmark still. 🙂

hi,

phewww.. this really helps a lot! I am a total maths-phobic person, not because I don’t like it, just because I have lost touch and feel just scared to go back. but seeing this, I can plan my revision accordingly! Magoosh, you’re always my favorite!

Pretty impressive and useful!

Is there a similar post for the GRE Quant section?

Thanks a lot,

Dan

Hi Dan!

Yes, there is, though it doesn’t take as many practice exams into account. You can see it here. 🙂

Mike McGarry certainly tries to make the lives of MBA aspirants easy! Thanks alot..

Dear Akarsh,

Thank you very much for your kind words, my friend!! 🙂 Best of luck to you in the future!!

Mike 🙂

Thanks for posting!

I am curious why the sum of the quant problems on Gmat Prep exam 1 and 2 are each less than 37 questions?

Dear Omar,

I’m happy to respond. 🙂 Remember that the GMAT Quant section always has “out of the box” questions — questions that are unique and do not fall neatly into any specific category. On any GMAT Quant section, there are always a few questions that will defy classification. That’s what happened on those exams.

Does this make sense?

Mike 🙂

Makes sense! Thanks, Mike!

Good job! Mike.

it would be nice,even if u had video explanation for verbal SECTION of OG guide,it would be very helpful for non native speakers like us. hope we will see soon

Hi, Veeramani

We’re working on getting those up as soon as possible 🙂 We’ll post about it on the blog when they’re ready to go!

Best,

Margarette

good work, really help full and after completing my OG and few practice tests. i noticed that mostly problems related to coordinate geometry and probability are getting wrong. rite now i just want to improve in coordinate geometry. someone suggested in your blog that when one figured out his week area, first he shoulld be well versed with fundamentals of the topic n next, practice number of problems ranges easy to moderate. but am not finding practice problems regarding co ordinate geometry(real gmat problems). i just had og and manhattan strategy guides, so pls suggest me what to do.and first of all just tell me 1) what are the testing areas in co ordinate geometry(types of questions frequently comes)

even am getting wrong in DS questions, generally apart from approach what will be helpful in getting problems correct(fundamentals or way i look at the problem or getting clear idea how DS OR on what it tests). the thing is if am out from this prob am almost done with math.and sure i will get 50+ in quant

Veeramani: I would recommend signing up for the Magoosh product: that’s where you’ll find all our questions on coordinate geometry. I see that, about a week ago, you signed up for the free trial but only tried a couple questions: that where you will find the questions, but now you need to sign up for the product to get there. We have a series of video lessons explaining everything you need to know about coordinate geometry, and another series explaining all the strategies you need for DS. Inside the Magoosh product is where you will find everything you are seeking. I hope this helps.

Mike 🙂

Wow, this is quite interesting! Thanks!

We’re glad you like it, I’ll pass your compliments along to Mike! 🙂

Best,

Margarette
