Did you do your Post-Course Assessment? This is a free 30-minute session to discuss your test results and come up with a post-course study plan. You do this in the 30 days after your course ends; you can sign up in the Office Hours section of the website.
Oh, wait I just saw that you've done 2 practice tests. Okay, you need to do the 3rd one in order to take advantage of that. How long has it been since you took your 2nd test? If it has been more than a few weeks, then it may be time to take the next test.
You also mention timing. Read this:

And then these two:

So here's your overall plan (for now). Use the below to analyze your most recent MGMAT CAT(s):
http://www.manhattangmat.com/blog/index ... ice-tests/Then come back here and tell us the results of your analysis and what you think you should do based on that analysis. We'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
If timing is an issue, spend about 10-15 days working on the stuff that the time management articles (above) talk about. Then take your 3rd CAT and sign up for your post-course assessment. (Your timing issues won't be totally fixed by then, but you'll hopefully have made some progress.)
