Is it Possible? Please Help!

Hello All,

I know this is my first post here, but I've been a long time reader/voyeur of this forum (it turns out you don't need to post much to benefit from it). Let me describe my experience, and maybe you can give some suggestions as I have a WEEK AND A HALF before the test! So my timeline looks like:

I started my journey the 25th of September by enrolling in MGMAT. I'm a full time employee at a tech consulting firm, so I have roughly 3-4 hours per day to study before the test on the 30th. My background is that I graduated from a tier 2 private engineering school in mechanical engineering with a 3.75 GPA, and I am a native speaker of English.

9/25 started MGMAT
9/25 MGMAT 41Q 31V - 590 (very rusty with all concepts as I haven't seen algebra like this in years)
11/27 MGMAT 42Q 27V - 590 (ran out of time on both verbal and quant- didn't know pacing strat)
12/11 MGMAT 44Q 40V - 700 (outlined but didn't write full AWA)
1/12 MGMAT 45Q 36V - 670

1/15 Finished all of MGMAT Prep Books, including Advanced

1/18 GPrep 48Q 34V - 670

My last test really has thrown me under the bus in confidence. I performed well in quant, only making 2 or so careless mistakes, however my verbal, my sentence correction killed me as I made mistakes involving idioms, and I had one rough RC passage.

As of now, my goal is to get 710+. I've already put in roughly 4 months of prep with around 120 hours of legitimate studying. In practice environments I get roughly 9 out of 10 SC questions right and 9 out of 10 RC (advanced difficulty). Is it possible, that if I study idioms and crank out verbal for the next week that I can bring my score to my goal by the 30th?

Any suggestions for some last minute tune ups or reading material that will amp my game up further? If I don't hit my target I will definitely retake. However, I'm discouraged by the stat that I've seen on this forum that generally the more hours you put into study, the more likely you will have a sub 700 score.

Please, any insight will be helpful.
