Fantastic job on the verbal!
Pointer #1 - you haven't actually been studying much yet. There's a huge difference between *doing* practice problems (which you have been doing) and actually studying / analzying / learning strategies for how to get better. You're going to need to identify some resources that explicitly teach you what you need to know (from both a content perspective and a "test taking strategies" perspective). Every test prep company out there has books that will teach you these things - and obviously each company will recommend its own books, so I'll let you decide (since I'm biased!).

Next, time management (which is also covered in the above article, but I'll repeat here). Read these two articles:

You could also pick and choose individual books based on your strengths and weaknesses.
You can use the below to analyze your most recent MGMAT CAT(s):

(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!) We'll then tell you what we think of your analysis and we can discuss strategies for moving forward.
