Most helpful test series

Test series by Experts' Global are a must for the following reasons:
1. They give you a topic wise breakdown of all the tests taken and help you identify the problem areas. There are graphs and charts that display the information in a very helpful manner.
2. There are 15 tests for a very low price. Hence you get the space to improve and reach your potential score.

A few cons:
1. The tests aren't exactly adaptive. I've seen easier questions after attempting difficult ones.
2. A few glitches in the software sometimes stopped my test after an hour. But once you reach out to the customer service, they'll sort that out.

Still overall, I highly recommend Experts' Global tests to improve your performance at the GMAT.
