In comparison to what I've seen when people post their breakdowns (I'm talking about the 20+ AA peeps), I'm pretty sure you got this. Most people don't do insanely well on their TopScore exams (there are a select few I've seen, but the majority that end up getting 20+ AA on the DAT seem to have similar scores to yours). Don't forget brotha', this is your first Topscore Exam. It's the perfect time to see what areas you're weak in and what areas you made silly mistakes in.
Having said that, I'm taking my exam in 2 weeks as well. If you think about it, 2 weeks is an INCREDIBLE amount of time to invest into studying for one exam. Just today alone I went through all of Chad's GC tests again, read 2 Chapters in Cliff's, and did a CrackDAT PAT test.
In 2 weeks time, you could go through Destroyer 2x, re-read areas you're unsure about in Cliff's (or whatever book you prefer), go through all of Chad's notes, go through all of Alan's Bio Notes, about 5 CDP tests, and 3-5 QR tests.
That's huge improvement. If a lot of the problems you got wrong are silly mistakes, then you have no reason to be worried. Simply correct the miscalculation/misinterpretation of the problem and instill it in your mind. If a lot of the problems you got wrong were due to not understanding the material, then, like I said earlier, 2 weeks is a huge amount of time.
You got this bro, I'm not worried about you.
