The GMAT CLUB CATs

Guys,
I got to hear about the GMAT Club CATs from friends who benefited extremely from them. I did some research online and found that the tests are designed beautifully to emulate the real GMAT exam.
The best feature of the CATs is its similarity to the actual test where in you get a true sense of the system adaptive nature of the test and it does help alot in one's preparation for the real exam.
Post completing the exam you get to experience brilliant statistics analysing your performance, strengths, weakness and correlating the same with the other test taker pool. This helps one gauge the overall performance and the weakness to work upon.
There is also detailed solution for the problems which helps one to reestablish the concepts and understanding of the same.
Overall, a great product which every serious GMAT aspirant must utilize to achieve excellence
