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?

Version 6.1 of the diagnostic test has been published. Changes: 1. Added several new questions 2. Rearranged some of the questions 3. Updated several online discussions Thank you for everyone's feedback!

I think question three should be rephrased. The PDF test reads "If X is an INTEGER" but the linked answer addresses the question "If X is a POSITIVE NUMBER", so the given explanation doesn't work. Same for question eight. The test question stem does not match the linked explanation. Thank you for putting this together!

I am new to GMATclub. I have finished my theory and now I want to give mock tests. Which would be the best mock test to join? Also, are there any free tests available?

Hello, I just took this test. I read #38 three times and I still don't understand exactly what it's asking, so I think this could be reworded. On #20, it leaves the possibility to test negative factorials, but from my understanding, that is not tested on the GMAT. On #12, the question tests you on whether you know that 0 is divisible by any positive number. According to a staff member's post on a MGMAT forum that I read, I believed this kind of 'nit-picky rule' was not tested? Overall though, very useful diagnostic!

Also, I noticed that #13 on the spreadsheet links to an old explanation.

Thanks for such a wonderful set of questions. Its of great help

Has this diagnostic test been updated to accommodate the typical questions that may be asked on the new computer-adaptive test? If not, is this diagnostic still a beneficial tool to determine my quant readiness level?

Yes, the diagnostic test is constructed to mimic the real test and questions.

Thanks bb for such a great effort. I believe taking this test in between the preparation would help much for the next step. Is the verbal diagnostic similar to this one already out?
