Hello,
Your numbers are by no means terrible, so I would not worry a great deal. One thing though is when you take the DAT make sure to score well in Ochem. This will show that you have shored those classes up and the C's are not reflective of you ability.
Be careful about taking classes at cc as many schools limit or dislike cc classes, (I have a lot of them). Bumping your GPA is never a bad thing though what I would do, especially since you are worried about grades, is submit early and include that class in your intended to take classes and give an updated grade in the fall to the aadsas.
Just my two cents. Good luck!
