It's true that some schools don't like to see 4+ test scores - but the major issue is that they don't like to see someone take it repeatedly without improving. And you are improving each time, so that's good.
You still might want to talk to an admissions consultant, though, about your situation and your admission profile. They'd be better able to advise you (my area of expertise is really just the test itself).
The two major points that jump out at me from your list:
- you've got timing problems (point #4)
- you're struggling with anxiety (point #5)
If you already know that you've got timing problems, then they are likely even worse on the real test, because you're anxious and know "this is it." And if you are mismanaging your time too much, then that's going to result in a definite score drop, because you're going to end up with strings of wrong answers at some point (due to running out of time) and that will kill your score.
So solution #1 is to work on that timing problem:http://www.manhattangmat.com/blog/index ... to-win-it/http://www.manhattangmat.com/blog/index ... anagement/

Solution #2 is to work on the anxiety. Tell me, have you been just as anxious all three times? Or have things been a little bit better / easier each time? (I'm guessing that just being exposed to the test process repeatedly helps at least a little bit - and your scores have been getting better.)http://www.manhattangmat.com/blog/index ... anagement/
The "In It To Win It" article (the first one I linked) can also help with anxiety because you can keep reminding yourself: I don't need to get everything right. I only need about 60% correct. So if I don't know this vocab word or this SC is too hard for me, who cares? It's only one problem. And one problem will not cause me to lose the match. (See the article and you'll understand what I'm talking about. :)
Finally, I know you're frustrated because you've been studying so hard and haven't gotten the score you wanted, but you have improved each time. The average improvement from official test 2 to official test 3 is 0 (zero) points. You improved 40! That's huge! I know it's tough, but you are really getting somethwere. You can feel frustrated and yet still feel proud at the same time. :)
