Let's work together as a community to create world's best GMAT Diagnostic test by creating, refining, and improving diagnostic questions.

We have started this project with the Quant section to help GMAT test takers understand their weaknesses better. The test is free - please take it. If you have any questions or suggestions - post them here. Also, the idea of the test is to improve it based on the feedback of the community - here is how you can share your thoughts:
1. Rate questions using the STAR rating system - the ones that rank low will be gradually phased out
2. Provide verbal feedback by replying to this thread
3. Suggest question types to be included in this test - please provide examples if possible (we'll take care of creating the questions)
4. Finally - get others to take this test and provide their feedback

How to use the Diagnostic Test - The Diagnostic Test is setup to allow you to test you as thoroughly or as quickly as you would prefer. The questions are arranged in sections in an increasing difficulty order - the first question is always 600-650 level, mid question is 700 level, and the last question is 750 level. If you are in a hurry, you can take either all easy or medium, or all hard questions only. Instead of 45 questions, you can only take 15 and leave the rest for later.

Taking the test
You should spend a maximum of 90 minutes answering 45 questions or if you are taking fewer then plan to spend on average 2 minutes per question


Where are the questions from?
The questions have been developed by very experienced and high scoring GMAT Club members

Are the questions copyrighted?
Yes, but you can post and distribute them to benefit other test takers - please give credit to GMATClub for the hard work our members put into this test

Great test, I'll provide more detailed feedback later...

P.S. Verbal diagnostic test is also much needed.

P.P.S. Thanks for this great site and all the materials that are shared by community members!!!

Thanks - will look into it.

I got a percentile score in the end, which was different from the % of correct answers. Is this relative to how others taking this test have performed?
Btw, the questions were very good and challenging although I could only complete 38 in the allotted time.

Thanks for putting this together. Fantastic stuff!

Hi,
I took the GMAT recently and received a score of 730. Your math test was very helpful in preparing me for the real thing. Kudos to all of you for putting together such a (dare I say it) beautiful array of math questions that was key to helping me perform so well.

Unfortunately, I am not that good at writing math questions! But I will submit at least a few verbal questions you guys can use later on. This is my own small way of giving back;

Thanks, it was a great exercise however in take online option, the question is different( i think its from before it was reworded) it asks to solve for 8small and 2large books, where he can choose 5 books but cant take 2 large at same time, wording was kind of confusing for me, i thought of it that he can take all 5 small books but then reading question it gave me impression that they want to take 1 large book hence i ended up finding probability for 1 large 4small books. Please see if you would like to reword that and clarify it little more.

Thanks for this effort

Extremely helpful with detailed explanations. I really appreciate your effort, BB. I think I may have noticed a question which could be worded a bit better, and I will reply back as soon as i review all of them. Thank you once more!

Welcome to GMAT Club!

Good luck with your GMAT Prep!

I did 42/45. What does it means? 49-50-51?

Thx very much for this very helpfull package!!!

bb,

You rock, as usual.....

bb,
It would be good to give some sort of "performance guideline" to the takers of the diagnostics.
I like what OG does; it has got "excellent", "above average", etc ratings based on the number of questions you got correct.

I believe it's coming soon. Can't state the exact date though.

Yes, this is indeed the next step.
My main challenge is deciding which algorithm to use - I have a few too many to pick from...

Thank you very much, bb. This is really great.

Brilliant!

BB,

Thanks for the diagnostic test! I have been studying for over six months now and I thought I had the quantitative part down... but it looks like I have a lot of studying to do!

I hope we did not mess too much with your confidence
Our diagnostic test and gmat club tests do happen to be on the harder side, so perhaps you should see it as an opportunity to get to a higher score faster or as a motivation to reach higher ground rather than something that puts you down. The test was created to challenge you rather than make feel good (which is actually an important part of the process) - you just have to keep that in mind. I hope it is not too de-motivating.

Nice presentation.
BB you are awsome. You rock!!!
