Keep taking practice tests.

To begin, each practice test will help you gauge your score trajectory and give you an idea of how long it will take to reach your target score.

Also, carefully analyze each practice test to identify your area(s) of weakness. There are four main areas of weakness you should watch out for:
1. specific Quant skills/concepts (e.g., algebra, standard deviation, etc.)
2. specific Verbal skills/concepts (e.g., verb tenses, assumption CR questions, etc.)
3. test-taking skills (time management, endurance, anxiety etc.)
4. silly mistakes

For the first two weaknesses, the fix is pretty straightforward. Learn the concept/skill and find some practice questions to strengthen that weakness. To focus on one topic at a time, you can use BTG's tagging feature to isolate one concept. For example, here are all of the questions tagged as statistics questions: https://www.beatthegmat.com/forums/tags/ ... statistics
See the left side of that linked page for more tag options.

If your test-taking skills are holding you back, then you need to work on these. For example, we have a free GMAT time management video at https://www.gmatprepnow.com/module/gener ... es?id=1244. Then you should hone your test-taking skills by taking more practice tests.

Finally, if silly mistakes are hurting your score, then it's important that you identify and categorize these mistakes during your prep so that, during tests, you can easily spot situations in which you're prone to making errors. I write about this and other strategies in the following article for BTG: https://www.beatthegmat.com/mba/2012/09/ ... n-the-gmat

Now, I should point out that a 230-point increase is 7 weeks is a huge expectation. I've heard of students pulling it off, but it's extremely rare. I certainly wouldn't make any concrete plans based on such a fast improvement.

Finally, you might consider signing up for Beat The GMAT's free 60-Day Study Guide (https://www.beatthegmat.com/mba/gmat-guide).
