I am still a rookie in this community. But, is was really tempting to reply to your post.
Many members of this community finds PowerScore SC
as helpful as MGMAT's SC
. You may give a try.
To me, comparatively, your verbal score looks better. As the test date is coming closer, try to reinforce your strength, and find out what is your weakness. Your error log
will do most of this job (and, it's what error logs are supposed to do!).
I think, if you take all other MGMAT practice tests (I guess, 4 are left. Right?), your score will find an unshaky base and will move close to higher 600s. Usually, the score you get in MGMAT tests represent your +/- 10% ability to score in the actual GMAT.
Good luck with your GMAT!
