GMAT Strategy

Q40 and V35 translates to a total score of 610 or 620. So, at the moment, you are short of your 650 target score. What has been your best score to date? I ask because I typically suggest that students achieve their target score on at least 2 practices tests before they take the official test.

It's hard to tell what you need to work on without knowing your weaknesses. With 11 days to go, your time should be spent strengthening any weaknesses you have identified. Many students have strong fundamentals, but their scores are dragged down by poor test-taking skills (time management and endurance). If that's the case for you, then you should take LOTS of practice tests.

If your weaknesses are content related, you need to focus on concepts that have the greatest return on investment (ROI). These are concepts that are tested frequently and require the least amount of time to learn. In my opinion, these concepts are:
- Sentence Correction
- Data Sufficiency strategies
- Percent
- Integer Properties
- Powers/roots
- Algebra
- Geometry

Notice that most of these are quantitative. I'm not saying that you shouldn't prepare for Verbal but for CR and RC I feel that noticeable improvements take longer, especially for non-native English speakers.

I hope that helps.

You still have a few days to reschedule (you can reschedule up to 7 days before the test for a $50 fee). Since it's been a while since your last practice test, I suggest that you take 2 or 3 practice tests in the upcoming days. See where you stand.

If those tests don't go well, THEN reschedule.

A 100-point increase in 4 weeks is quite significant. I've seen it before, but it's not that common.
Start taking practice tests so you can gauge your progress/trajectory.
