I took gen chem I and II at a different college then the one I am attending now, three years ago, and received C's in both. My question is can I retake those classes at my current college or should I retake them where I last took them?
If you want to retake them. Take them at the school your currently at. Even if you take them at the same location your probably not going to get the same professor anyways. Take it where it is easiest for you and where your currently going.
Retake them anywhere you'd like. Although both grades will appear on your AACOMAS transcript, only the most recent grades will be used to calculate your AACOMAS GPA.
