Agreed that your current score is in the 600 to 640 range.
You've been taking tests pretty frequently (even discounting the botched test). I want to make sure that you're aware that the act of taking a practice test really doesn't do much to improve your score. 98% of what you learn comes after the test is over, you analyze it, and then you spend the next couple of weeks working on whatever weaknesses became apparent as a result of that test. The next test is then used to gauge whether you've made progress, and where, and to come up with a new list of strengths and weaknesses to tackle.
For your timing issues, be aware that there are two fixes and which one you use depends on the circumstances of that particular problem type or content area:
(1) learning to be solve more efficiently (works best if you are getting the questions correct more often than not and if you're not going more than about 45 to 60 seconds over, maybe up to 90 seconds)
(2) getting the questions wrong faster (works best for any that you're getting wrong anyway, and for those that are going 90+ seconds over regardless of whether you're getting them right or wrong)
In other words, the fix is not simply: learn how to get this right faster. Sometimes the fix really is just to get something wrong faster. :) Also, factor in the frequency with which something is tested.
Of the topic areas on your first list (quant timing issues), these are more commonly tested:
pos and neg
stats
linear equations
So those ones are more worth prioritizing into category 1 if you can. The others are less common (especially sets and rates), and so those ones are typically a better for for category 2.
For your second list (quant accuracy problems), these are the most frequently tested:
fractions
divisbility and primes
percents
Of that set, the most infrequently tested are rates and the geometry stuff.
I notice that rates are on both your too low and too slow list, so there's your first candidate for category 2 (get wrong faster).
verbal section SC is stuck at 60% accuracy overall and CR at best 50% to 60% accuracy
This isn't really going to change much as you get better (unless you eventually lift yourself into 90th percentile plus territory on verbal). The percentage correct is not what changes (much) as you get better. Rather, the difficulty levels get higher.
So that comment tells me that you need to learn more about how the scoring on this test works. Read this article as well as the Scoring section of our free e-book The GMAT Uncovered (if you have an account of any type with us, the e-book is already in your student center):

Re: your question of how to lift verbal the last few points, read this:
http://www.manhattangmat.com/blog/index ... an-part-2/You're at the "learning how to think" stage described in the article. It's not primarily about doing a million questions now or learning a bunch of rules. It's about learning how to think, as the article describes.
Finally, you ask me whether it's possible to improve by about 50 points in the next 5 weeks. Yes, that's possible. There are no guarantees, of course. Again, take a look at that last article about how to study - you need to make sure that the time you're spending is as productive as possible in that you're learning how to think through these questions. If you're struggling with that level of study (as opposed to the more content-focused study described in the article), then you may want to get some outside help in the form of a tutor. (I'm suggesting a tutor, as opposed to a class, because you don't have much time left. I'm also suggesting a tutor as opposed to a friend because friends who did well can often help with content-focused study, but people who aren't trained as teachers find it much more difficult to help a friend with the "how to think your way through" issues.)
