Hi,
I purchased the GMAT official guide quantitative review 2020, and wanted to know if the questions in the mobile app and website are the same as those in the book?
Would you say the level of questions in the guide is equal to the real test or easier?
Also, what is another good source for quantitative questions and test simulations?
Thanks!

Hello,
adiki. I agree with what has been said above. To answer the second question, what you see in the guide is quite reflective of what you can expect to see on the actual exam. Since the guide starts with Easy questions before working its way up to Medium and Hard questions, as officially categorized by GMAC™, again, you can get a feel for how you might perform based on whether you can navigate the Easy questions with ease and maybe make just a few mistakes in Medium questions so that you would likely be spending your time working on Hard questions on the real test.
For additional Quant questions, again, I have to agree with what I have seen above: look no further than GMAT Club. Many high-scoring (50-51) test-takers have, in their debriefs, gushed over how helpful the GMAT Club Quant questions were in their preparation, even if these questions tended to be harder at the upper levels than those on the actual test. This is not to say that you cannot look at other sources for practice, but when many people offer praise for the same sources, the wisdom of the crowd tends to hold true.
Finally, for test simulations, you can take third-party CATs, such as those by Veritas Prep or
Manhattan Prep, for additional practice, but these are
not substitutes for the six official practice tests you can access through mba.com. Those first two free (official) tests are like gold in your hands, so do not blow through them before you are ready. All the official practice tests are by far the most accurate predictors of your eventual performance.
If you have further questions on any of these matters, feel free to ask. Good luck with your studies.
