Great number of practice tests

Experts’ Global’s GMAT mock test series is great value for your money. It has 15 tests for only 50$. No other test series provide so many tests and that too at such an economic value. The tests give an incredibly detailed analysis of your performance. It clearly highlights topics that need improvement along with your strengths, type of questions you are making mistakes and charts on difficulty vs accuracy. This gives a clear view to identify if you are getting easy questions wrong vs difficult questions wrong.
It also analyzes your most recent performances to determine which areas you need to focus the most on and which you can afford to be confident in. It also gives you the average time you take per question, so that you can improve your time management as well. It clearly lists out difficulty wise accuracy and that helped in my preparation as I targeted to ensure I get the ‘Easy’ questions 100% right.
Each exam comes with a detailed video explanation of every question. It also shows quick and easy ways to solve the question within the ~2 min timeframe. I ensured that I watched the video explanations for all the questions, even for the ones I got correct. This ensured that I got the question right for the right reasons and solving them in the optimal way.
The questions cover all the same concepts tested in GMAT and are alike in difficulty/complexity.
I was able to only cover 10 of the 15 mock tests where my scores ranged from 700-740. Finally I got a 720 in the online GMAT exam. All in all, I found this test series to be a great resource that really helped me improve my GMAT score.
