Hello!
Interesting thread.
EG mocks
'and' Official mocks (rather than EG mocks
'vs' Official mocks) is the correct approach

We recommend taking our mocks earlier in the prep, when building concepts/stamina and knowing/working on your weaknesses is the primary aim (because explanations and analytics in our mocks are more detailed than the official ones).
The official mocks should be reserved for closer to the test, when knowing your exact level becomes critical.
Regarding the difficulty of our mocks, please note that all our mocks simulate the test experience for the 90th percentile and above. Hence, if a candidate is at a lower level, one may find the tests a bit difficult. Our scoring (and not ordering) is adaptive, so one still gets a reasonable estimation of one's true level on the GMAT. Since the purpose of mocks is to prepare students for the eventual test, practicing on a difficulty that one would consequently encounter on the GMAT (en route scoring 655+) is helpful. This is our thought behind designing the mocks and this approach is generally much appreciated by students.
Rest, you can read reviews of genuine students who took our mocks as well as the real GMAT, here:
