as to me, the score of Kplan is not necessarily a good indicator of your GMAT score..so don't worry too much about the score...I think the most important reason that we do Kplan is to prastise our pace in the GMAT test, not to predicate our GMAT score...If you want to know your realy level in GMAT, I think the most reliable way is to do the OG, which is quite similar with real test...
