General GMAT Questions and Strategies | Re: How accurate is a surprisingly high result from the Prep Test?

Hi all, Thanks for yourreply
HanoiGMATtutor : Fellow countryman, I'm not what a diagnostic test is -_- probably the test in the official book? I took it and got excellent for Quant and CR, but only above average RC and SC . I found it surprising because I have put only a few efforts in GMAT and with this very good result I'm not sure about which areas I need to improve, or maybe I should take the testalready.
