Yea, you can definitely be admitted. I applied early fall 2011 and I still had 12 outstanding prerequisites. That's pretty much 5 sciences each semester and 2 in the summer before I matriculate into OD school. I don't recommend doing it that way, but it's certainly possible if you don't want to wait a year. I was accepted to all of my top schools, but conditionally (I have to finish my classes, of course). Also, my gpa was good - if you apply as unfinished as I did, you're asking the school to bet quite a bit on you. You'd better have a good history, ya know. The most important thing to consider is whether or not you're ready to start OD school - apply when you're ready.
