A 700-point increase in 2 weeks is a big leap. That said, you can reschedule your test up 1 week before the test day, so you might consider taking another practice test in a week or so to see where you stand. I typically suggest that students achieve their target score on at least 2 practices tests before they take the official test.

To improve your score, it's important that you identify and strengthen your weak areas. One way to do this is to use an Error Log (aka Improvement Chart) while completing questions from the Official Guide (OG). You can find a free downloadable Improvement Chart here: https://www.beatthegmat.com/mba/gmat-error-log
