Good work so far - you're making solid improvement. I have to let you know that most people would need more than two weeks to pick up another 60 to 80 points improvement, even studying full time. There are certain things that just can't be crammed on a test like this; it isn't a measure of the
quantity of your preparation.
Do you have the ability to postpone your test? If so, then I would recommend doing so. If not, we'll still go for it, but you should expect that it will be very difficult to break 600 in such a short timeframe.
In order to advise you, I need to get some more detailed data on your strengths and weaknesses. Use the below to analyze your most recent MGMAT CAT(s):

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!)
Also, most people find that they do struggle with timing on this test. If you do as well, that's good news, because timing can sometimes be fixed more quickly than other things (though it still typically takes a good 4 to 6 weeks). Here are some resources that can help:
