Experts’ Global is the GMAT mock test series that does best job of simulating the GMAT. My overall scores, sectional scores, and even number of mistakes committed in their mocks were in complete correlation with the same on the official mocks and later on the real GMAT (as per my ESR report).
What first drew me to this firm, however, was not the quality but the quantity of their tests (I needed lots of tests

).
Experts’ Global’s mock series has 15 tests in total, more than twice what most other firms offer for this price.
I was also drawn in by their promise of a stellar weakness analysis system, which they delivered upon spectacularly. The software was able to identify my weakest and strongest areas very effectively. This really helped motivate me by making it clear what shortcomings I needed to conquer, in order to get the GMAT score that I needed. It was also quite convenient to have an automatic analysis done for me rather than having to do it myself. This analysis also helped me a lot with my time management. The software told me the time taken for every different type of question, time taken in the slowest few and fastest few questions as well as well as the accuracy for the same. This analysis helped me realize that taking more time was not necessarily leading to better accuracy and I learnt to keep moving on while attempting the tests.
Getting back to my initial point, the questions in the
Expert’s Global mocks are carefully written to be as much like the real GMAT questions as possible. The difficulty levels are maintained at the GMAT level and the scope of concepts covered remains parallel at every point. As I mentioned earlier, all of my scores on the mocks, including sectional scores, matched my scores on the GMAT Prep mocks and later on the real GMAT as well. As far as I can tell, absolutely no other GMAT mock series can boast of such accuracy, as the GMAT scoring algorithm is not publicly available.
The questions are also backed up with video explanations, for the questions that you are unable to answer. These videos are, however, also good to watch even if you have gotten the right answer as they all take great care to provide the simplest and quickest solution possible. I picked up a lot of time savers from these videos.
Overall, this is an amazing test series and all GMAT aspirants should at least try one of

I used to spend good 1-2 hours on pure analysis of my performance- in mistakes as well as time management and the learning was crucial to my gradual but consistent improvement over several months. The review option of Experts’ mock tests is a great feature, it gives you a threadbare report of your performance- make the most of it!
