I dont think that you will have a problem getting in once all your classes are done. When I called and spoke with them, they said that they first pick the students that have all the classes done (and the grades are good)... then they pick people with one class left to do... and so on. They really want you to be done with all your sciences. That is what they look at the most.... your grades in science. Since you will still have 2 science classes left (technically 4 with the labs) you are in the same boat as me. I have micro and nutrition left which I am taking in the fall. I am not getting my hopes up that I will be getting in, for that reason. I know they get hundreds of applications.
I also know that your TEAS score doesnt matter as long as you just passed. When I went to the nursing meeting... they specifically said that you dont have to take the test 10 times. As long as you pass... you pass. They dont care your score.
Just stay positive as best as you can. Dont put all your eggs in one basket. Look around to other schools (locally). If you are going to have to wait to start until 2013... you might as well go right for your BA. That is what I figured and started looking at schools. 4 year schools dont have any requirements as to what needs to be done. You just enter if accepted. Yes... it is more $$$ and takes longer, but chances are you will have to get your BA soon anyway.
Good luck... I hope that you get in!!!
