Hello zzxxdd,
Exam stamina is probably the key factor to achieving your goal. We see plenty of people who have the technical capacity to do well on the GMAT (or other tests) but are unable to reach his/her goal due to the stress of the test.
You need ~4-5 points on quant and ~7-8 points in verbal to reach the 700 barrier. The good news is the math on the GMAT tends to be harder than the real thing. We have had people who scored 44 on
MGMAT quant and then scored 51 on the real GMAT quant.
Unfortunately, the above is NOT the case with verbal. Go through and assess your verbal results and figure out how to address the topics there. Use an
error log to monitor and benchmark your progress.
Best of luck,
