Thanks for re-posting in your own thread - it makes the discussion much easier. :)
Okay, so quant is fine but verbal is the problematic thing - that's what dropped on the last GMATPrep test. I do have to warn you that the same thing could happen on the real test because a week isn't really enough time to address issues that can lead to a big score drop, but you might still also hit the scores that you were hitting on your previous tests before that one last lower test.
One thing I'm wondering is whether timing might have been an issue - that can often cause a big fluctuation in score. You mentioned struggling with SC and some CRs. Did you get a little hung up on some, spending extra time because you found them harder? That would have caused you to have to rush on other questions elsewhere in the section, which would increase the number of careless mistakes. (And you did mentions seeing some tricky questions that you didn't feel were tricky while you were doing them but then afterward you realized you missed something. Rushing even a little bit could have contributed to that.)
I'm also wondering whether stamina might have been an issue. What had you been doing earlier that day and in the couple of days before? It looks like you were taking a ton of practice tests back to back, which can hurt your mental stamina. Did you ever find yourself either feeling sick of the test (I don't care anymore, I just wish this was over) or reading something and then realizing you had no idea what you just read and re-reading it again? Those are signs of mental fatigue.
So. Today's the 15th, you're booked for the 19th. We're going to take the view that stamina and some timing problems contributed to the score drop, but that you're also capable of scoring in the high 600s because you did several times.
DO NOT take another practice test. The BEST scenario is that you do get a score in the high 600s, but you tire yourself out again right before the real test, risking another low performance on the next test (the real one). The WORST case scenario is that you get another low score and that kills your confidence going into the test on the 19th.
Actually, I'm going to amend that to this: if you think that you would actually postpone your real test if you get a 2nd low score, then go ahead and take a practice test today (
not after today - too close to the real test. But if you know you're going to take the test on the 19th no matter what, then don't take another practice test. Just assume that we've figured out what's going on and we're going to deal with it.
For others reading this, the general rule is: no practice test within 5 days of the real test.
So how do you deal with it? By doing less and resting your brain. Do high level review of everything, but don't do a bunch of problems and overload your brain right now. You know what you know and you don't know what you don't know, and that's not going to change in 4 days. So review and get your brain ready. The closer you get, the less you do.
Read these two articles. You aren't going to do everything that's written here, obviously, because you don't have 2 weeks, but they'll give you a good idea of how to review in the last few days leading up to the test:

You've got to be REALLY careful that you don't go into the real test thinking that you have to get everything right, because then you'll blow all your time on really hard questions (which you'll probably get wrong anyway) and then you'll get a bunch of easier questions wrong that you could have gotten if you'd actually had the time... and then your score will drop.
Read this. Do what it says. You don't have much time, so you're just going to have to trust me on this one. :)
