I have consistently been scoring in the 630-640 range for the past 2 months, across 3 MGMAT CATs and 1 GMAT Prep CAT and have not seen any improvement in scores. This is really frustrating as I have completed the MGMAT Course, have been consistently studying over this time, and have gone through a significant chunk of the OG questions. I have also worked on improving my timing over this time and implemented the MGMAT water-tight timing techniques on these practice exams.
My practice scores are listed below:
June 7 - MGMAT CAT (Diag) - 510 Q28, V32, 34th percentile
July 15 - MGMAT CAT - 590 Q37, V34, 58th percentile
Aug 24 - MGMAT CAT - 630 Q42, V34, 71st percentile
Sep 8 - MGMAT CAT - 640 Q40, V37, 72nd percentile
Sep 20 - GMAT Prep - 630 Q44, V32, 72nd percentile
Oct 6 - MGMAT CAT - 640 Q42, V35, 72nd percentile
Round 2 deadlines are fast approaching and I don't know what I need to do to improve. Please help!
