Great job on verbal!
For the quant, you do want to target weaknesses, not just review everything. In particular, you want to target the "low hanging fruit" weaknesses:
1. Careless mistakes: you already know how to do these, but maybe your mechanics need some work, or you need to build the habit to write everything down, etc.
2. Holes in your foundation on commonly tested topics. Don't worry about things that aren't that common, such as combinatorics and probability. If you're struggling with exponents & roots, though, then you need to study - those are common. See below for a list of common topics.
3. Correct but too-long answers. If you spent 2.5 to 3.5 minutes, can you learn to do this in under 2.5? If you spent 3.5+ minutes then it would've been better to get it wrong faster. (Seriously! You potentially cost yourself
multiple other questions when you spend that long to get just one question right.)
The wrong and too slow ones are NOT a priority to improve. Shrug, get them wrong faster, and use that time elsewhere.
You can still work in a more comprehensive review while you work on the above 3 areas. When you're going to do a problem set, include several problems in areas you've been studying AND several randomly-chosen problems. If you do that frequently, that will constitute a large part of your review - get it right in a reasonable amount of time, great. Get it wrong, take too long, whatever, and then you know you need to review that area and decide whether you need to study, whether you should have got it wrong faster, etc.
If you want to do a more in-depth analysis (and I recommend it), you can use the below to analyze your most recent MGMAT CAT in great detail (this should take you a minimum of 1 hour):

Also, feel free to come back here and tell us 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!)
