GMAT Strategy

Hello,
The following are my CAT scores thus far (WITHOUT IR/ESSAYS):

2/10: GMAT PREP : Q:47, V:34; 650
3/12: MGMAT CAT 1: Q:44, V:33; 640
3/24: MGMAT CAT 2: Q:44, V:36; 660
4/7 : MGMAT CAT 3: Q:38, V:33; 590
4/14: MGMAT CAT 4: Q:45, V:32; 630

All these were taken under the actual exam conditions. (with the exception of not taking the IR/AWA sections).

I have 5 weeks to go before D day.

1) Are MGMAT CATs tougher than the real one? Or are these scores pretty accurate? (I understand all the above scores are inflated because of not taking IR/AWA - but I haven't completed preparations for IR/AWA yet).
2) I have been mostly working on completing OG questions this past month and although I have been taking one practice test a week, I haven't particularly focused on weak areas (which I have identified as CR and DS across all math topics questions and definitely time management on Verbal). Are my scores not improving because I did not sufficiently focus on just these 3 areas? I was intending to complete at least one pass of the MGMAT books and the OG before drilling in to the weakness areas. I am beginning to wonder if my study strategy is not working.
3) I am aiming for a 700. Is a 700 even feasible given the amount of time left?

Thanks,
Archana

Option A: Would suggest you to study for 4 weeks and give GMAT Prep 8-9 days before your scheduled date. If your score is less than your desired score by more than 10 points i.e if its 680 or less then you can postpone your GMAT by paying 50$.

Option B: Postpone today by 1-2 months based on your speed of improvement till now.

Choose option A if you perform well when you have deadlines and chose option B if you learn better when you are relaxed. Also consider whether dates are generally available in your location.

The MGMAT CATs are a little tougher on average than the official test, so those taken without IR/Essay are an accurate measure of your current abilities.

You should always be working on time management - ie doing timed problem sets whenever you practice. This is not a weakness that can wait until later in your prep.

Your scores are probably not improving because you are not prepping optimally. Check out my guide to self-study GMAT Clarity (amazon link) for this.

700 is definitely possible in your time frame if you improve the quality of your prep.

Thank you all for your comments and suggestions.

Thomas, would the guide be helpful even for folks like me that already completed my MGMAT Strategy guides and taken a bunch of CATs? I am obviously not focusing on the right preparation strategy here (looks like it, since I am stuck in the lower 600s for a while now). I have been preparing for almost 4 months now. Although I try to spend at least 4-5 hours a day, it has been tough with an infant at home and several other personal chores & constraints. I do have the luxury of pushing out my test (if need be). I am only applying to one school (again - family/location constraints) and absolutely need a 700+ to have a decent chance. So I really just have one shot at this.
