Is it worth to redo official mba.com cats?.

Also the 9 paper test which gmac offer is it worth to do that ?.

Among tutors, there's no consensus about the value of resetting those official tests. I think it's worthwhile; just bear in mind that you are likely to see a handful of repeat questions, so your score may be artificially inflated. My advice: if you see a question you recognize, allow a full two minutes to go by. Then be honest with yourself. If you think you'd have answered a similar question incorrectly, intentionally get it wrong and make a note to yourself to review this category of question after the exam.

As for the 9 paper tests, my feeling is that there is better material to review. I'd prioritize the question bank from mba.com and the questions from the Official Guide before I'd consider dipping into the paper tests.

And there is no need to do unofficial cats like Manhattan a redo.

Hi november22,

I have to agree with Rich here. While practice CATs are an important part of any study plan, they should be used to highlight any areas in which you need to focus your understanding, as well as any timing issues you might be having. They should not, however, be the only prep materials you're using. You'll gain a great amount of insight into how you might anticipate performing on test day, but be sure to include additional materials that will help you understand concepts and test-taking strategies as well.

Best,
Rich

It can be useful to redo the GMAT Prep tests, IF you are honest about the effect any repeat questions are having on your performance. Still, especially if your skills are increasing, you will likely see few repeat questions.

Having said that, I can tell you that I have heard about high practice test scores which were not matched by scores achieved on the actual GMAT. THEN I find out that actually the high practices test scores were achieved via multiple retakes of the GMAT Prep tests, and that's much of why the practice tests scores were so high.

So I suggest not doing that.

By the way, if you have not used the Official Guide thoroughly, you may want to try the tests in PowerPrep, the software that preceded GMAT Prep. While sentence correction has evolved since that software was produced, for the most part the tests it generates rather accurately create a GMAT experience.

The thing is there is crossover between PowerPrep and the OG. So if you have done every question in the OG, you will run into repeats in PowerPrep.

You can download PowerPrep from here. https://www.beatthegmat.com/mba/resources

I would agree about not repeating tests on the current version of the software, but the older version of the GMATPrep software (not to be confused with the powerprep software) is a different story. I don't know exactly what happened when they went from the old version (which was only PC compatible) to the new version (the one that was released when the test changed in 2012), but it seems that they removed a lot of questions from the pool. On the old software it was possible to redo the tests multiple times and see very few repeats (I would say at least 3 times for each test).

So I am sure that the old version of the software can be found online somewhere and that definitely gives one the opportunity to repeat those tests without significant repetition (again figure about 3 times per test before the repeats become significant).
