does reinstalling mba.com's gmat software give new tests?

Nope.

You will not get new tests, but can get new questions. To clarify, you will definitely get some repeat questions - but also a host of new ones. I have taken the GMAT Prep Test 1, 4x and yes by the fourth time you have seen over the half the questions, but there are still new one that make it worth it, as this software is the closest thing to the real deal. You don't need to re-install the software. After you have completed a test and reviewed your answers and want to re-take, when closing the program it asks you something like do you want to save where you are - say no, close the program and then open it again and click on the test you want to re-take. Of course, when retaking your score and timing is inaccurate as you have seen so many of the questions before, but even the 5-10 new questions you see after multiple attempts makes it worth it from a learning perspective

No it does not.

Hi,
I have to respectfully disagree. I myself have been able to take both GMAT Prep Tests 4-5x.
For further proof below is an excerpt from user TedCornell
“GmatPrep Test often: Unfortunately the GMATprep software has only 2 tests, but the last few weeks before my exam, I kept deleting and retaking the tests simply because they’re the best available. Some people don’t like that because they will see some of the same questions (true) but I felt the upside was too good to pass. After taking the test 4-5 times, it’s true that your score will be inflated by the questions you’re familiar with, but you will still see many new questions and ultimately I think GMATPrep is the only test that actually has the authentic content that you will face on game day. 4 weeks and earlier before your exam, you can take other tests, but I think from the 4 week mark in, you should take only GMATPrep. Ignore the score, focus on the content. Even if you see a question you know, hold yourself accountable for solving it rather than just picking the answer. I just told myself that I wanted to consistently score 40-50 points above my target score, so I kept taking GMATPrep and mastering its questions. I had a 770 my last GMATPrep and a 750 on the actual GMAT.”https://www.beatthegmat.com/from-610-to- ... tml#131975

Here's the deal: There is a difference between retaking the tests and reinstalling the software.

When you download the GMAT Prep from mba.com you get ALL the questions... I think there are about 1000 questions... that GMAC published for GMAT Prep.

But if you do the test once, you will see only 78 questions. Do the math -- there are hundreds more questions left in the question bin so repeating the test will naturally show you many more questions but there will always be some you have seen before.

If your purpose is to replicate the test day experience, you can propably get away with repeating the GMAT preps twice each... with a significant amount of time in between the repeats.

If your purpose is to see new questions and to see very difficult questions and master them then simply repeat the the test 10 times/ 20 times whaterver. You will see more and more repeats (esp in Verbal) but there will always be a few new questions. There is value to doing this because you access the very difficult questions. But if you get a 770 in your 7th retake and you saw 18 repeated questions it would be unreasonable to expect a 770 on test day (unless of course, you were scoring 770 in other tests).

Reinstalling the GMAT Prep software will still give you those same 1000 questions you had the first time you installed, so it is a waste of time.

Hope this clarifies things.
