Thanks guys. After much consideration , feedback and personally trying the free tests of both GClub & MGMT, I have decided to go with MGMT for improving my Quant.
I really liked the explanation provided by MGMT vis-a-vis GClub tests. Moreover, I have observed (from 30 samples of people who have taken MGMT) that their final Quant score in the Actual Exam is ~ 3 points higher than the Average of their last 3 MGMT tests. Even Verbal seems to be at par - but their are couple of conflicting points I have observed w.r.t MGMT Verbal.
Gclub tests - They have good number of tough & tricky questions but I was not comfortable with their explanations.
So for Quant - I am going to use MGMT tests to sharpen my skills
And for Verbal - I am going to stick to E-Gmat and OFFICIAL Questions only. I will buy the Question pack 1 & Exam pack 1.
Best Regards
