I agree with the above. It really depends on your work experience, letters of recs and PS to compensate for a weaker GPA. Numbers are only a part of the picture, but it would be helpful if you had some recommendation letters that can vouch for you. If you've been out of school working and gaining experience, that would help as well.Just a couple of questions...
1) Are the science classes you retook going to be factored in your GPA?
and 2) How long have you been working as a rehab aide?
Depending on those two things, it'll be easier to give you some advice. For a very low GPA, I honestly think you're better off cultivating a lot of work experience and using that to help boost your application (with LORs from supervisors/employers mainly).
