Ga Perimeter College has classes and you can probably do them online, and just go in for lab if you need a science. They, too, are extremely unorganized and a bit of a headache, but I was able to get a few extra classes out of the way there.
I made an 89, I think, on the TEAS. I have good grades, I did have to take English over again, but they only take the higher grade. Some schools average them together. You should aim to have somewhere close to a 3.5 to get in, if not you prob need to re-take some classes.
