We can't tell you anything because we have no clue what your grades are. It is all averages.
Not to be mean, but honestly you are wasting your time and money applying. Optometry is heavily focused in science and having such a low science GPA does not lend much credence to you. You need at least half a point to even have a chance. It is going to be incredibly hard to do such a thing. Besides, this is simple statistics- if you can't figure out simple statistics, it makes me not only question if you have taken statistics (which is a requirement), but it makes me question how you will do well on the QR section of the OATs (and the OATs in general for that matter).
I'm sorry if I come off as mean, cruel, etc. but this is the harsh reality. You don't have a chance of getting in and taking a few classes at a community college will not help your GPA enough.
