I did the gmatclub diagnostic test and did reasonably well. Going to take the 2nd real gmat prep CAT tomorrow and see how I do. I do not trust the mgmat CAT stuff at all.
Cool that you are doing the CFA program. Just passed lvl 3 in Aug.
Big congrats, must be a huge weight off your chest! Good luck with your CAT tomorrow. Take mgmat CAT's for practice purposes only, do not worry about score too much!
It's a dawg eat dawg world.
