For the scores you're posting, I'd say that the feeling that you're guessing on half of the questions is a bit high (though it looks like you're pretty good at guessing!). Most people have to do the "clicking and praying" thing on maybe 4-7 questions per section and then there are also some for which the person is reasonably sure they've got the answer (or narrowed it down to two) but not 100% confident. At the same time, I'll also say that my students often tell me they think our quant is harder than the quant on the official test.
Given that your GMATFocus scores are also up and down, I'm guessing that you have certain areas that are very strong, fundamentally, but you also have certain areas that are "holes" in your foundation. When you get more questions that fall into the "holes," your score goes down.
Go back through the last couple of tests and GMAT Focus questions. On what types of problems weren't you really sure what you were doing? What part of it threw you off? Did you not know the fundamental content well enough or was it more that you weren't sure how to interpret what they were asking or what they were telling you? Keep a log of your responses and look for patterns. If there are some holes in your fundamental content, go back and plug them. If you're struggling with interpretation of "what is it they're saying here exactly?" then study the language / setup of OG, GMATPrep and GMAT Focus problems to start to get a feel for: oh, when they want to ask about this topic, they tend to use these words, or when they want me to do this series of steps, then they tend to use this setup. Eg, when they want to talk about prime without using the word prime, they might say something about the number of factors (primes have exactly two factors) or they might ask whether there is a factor n such that 1 < n < x. If x does have a factor n between 1 and x, then that number isn't prime. eg 1 < 2 < 6. If x does not have a factor n between 1 and x, then that number is prime. eg 1 < ? < 5.
On that GMATPrep test - did you see question repeats that you actually remembered / recognized? If not, then you can count that. If so, then yes, you should discount your performance a bit.
You'll have to make the decision ultimately, obviously, but you're scoring well enough that I'd be inclined to take it and see what happens. If you still have time to take it until mid-Dec, that gives you an opportunity to take it a second time (you have to wait 31 days to take it again). So, if you take it this month, I'd view it as a dry run, see what happens kind of deal. Reduce the pressure. :) The mindset is: if this works, then I can spend the next month focused solely on apps. If it doesn't, oh well, I'm back to my original thought, which was to take some more time to solidify my math. I haven't lost any ground there. And I'll have the experience of having been in there once and knowing what I need to do the next time around. (Note: do this if you really can maintain the "let's see what happens" mindset. If you think you'll be super demoralized if you don't get the score you want the first time, then you shouldn't do this.)
Re: the practice test advice, again, obviously you need to make the decision for yourself, but I strongly discourage my students from taking a practice test within 5 days of the real thing. Practice tests are for learning. It takes at least 5 days (if not longer) to figure out what you should be learning from a practice test and incorporating that into your arsenal. (So I also wouldn't take another test a day after I just took one, by the way.) If you aren't actually spending hours combing over a test, and using the data to hone your strengths and rectify your weaknesses, then you're not really learning much from that test experience.
