Just took baseline CAT (640) - need help w/ a 2-month study plan

Hi Team Gmat,

I decided to take the plunge this weekend and get in full GMAT prep mode, hoping to take the test in 2 months based on my work schedule. Briefly, my background is a 25 year old American who works professionally in communications.

To get a true baseline, I took the GMAT prep practice CAT this weekend before cracking open any study books (did study GMAT materiel for 2 weeks about a year ago). While I skipped the practice AWA, I did the rest of the sections consecutively in a test like environment.

Score: 640
Quant: 39, with 40 minutes left
Verbal: 38, with 30 minutes left
IR: 4

I'm not too worried about IR - I was completely unfamiliar with the format and a quick review of my errors makes think a familiarity with question structure will help alleviate the low score there.

My bigger questions:
- Does a 2 month time table sound reasonable?
- Are there strategies to make myself use more time? (rare question, I know)
- What materials should I be using to study? (Currently have a 2014 Kaplan GMAT PREMIER and a 13th EDITION GMAT REVIEW)

I'm planning to dedicate 2-3 hours on week days and 4-5 on Saturdays and Sundays
3 weeks Math
2 weeks Verbal
1 week review IR and AWA
2 weeks test practice and review of error log

Any other input would be helpful. I've tried to do as much reading on the GMAT test prep subject this weekend, but I realize everyone needs to approach the test a little bit differently.
