I've been considering taking the 9 course in-person class that starts in mid September.

In the past year, I've gone through the 7 Strategy MGMAT books twice (all but RC). The first time I went through, I did both normal and advanced sections. The second time through, I only reviewed the normal section. I was getting a relatively high verbal score on my MGMAT Cats. I've taken all 6 already. However, I felt that the MGMAT cat verbals were not a good indicator of my verbal ability, since my GMATPREP2 and real GMAT verbal scores were a lot lower (please see below). I have also gone through the OG12 and supplemental books twice sans the RC section.

Anyway, my question is whether you think I will be able derive some value out of the course that will help improve my score? Or have I done most of the prep work that the course will cover? I mean I am sure I will be able to get something out of it, but is that something worth the time and the money invested?

I also signed up for e-GMAT and have begun going over that material as well.

My main weaknesses in verbal are mid - high difficulty CRs and high Difficulty RCs. My main weaknesses in Quant is my inability to solve mid-high difficulty questions within 2 mins and my trouble with solving mid-high difficulty DS questions. I am currently enrolled in the e-gmat verbal program, which I started last week. But I am thinking of adding your 9 course MGMAT section as well.

7/1 550 (Q32, V33) gmatprep 1 (baseline)

4/7 680 (Q44, V38) gmatprep2
4/26 620 (Q42, V34) gmatprep2 (retest on the new gmatprep 2.0 software)
4/30 590 (Q40, V31) real GMAT (had to pee in the middle of verbal)
7/14 670 (Q42, V39 IR 3.87) mgmat 3 (ran out of time on the last 2 verbal questions)
7/21 660 (Q42, V38, IR 3.73) mgmat 4
7/24 710 (Q47, V40, IR 4.57) mgmat 5
7/28 700 (Q44, V41, IR 0) mgmat 6
