Transferring to a CC to take classes after you have started taking them at a university (you didn't specify either way) is a major red flag. It can look as though you are trying to maximize your GPA by taking hard classes at easier schools.
If you are taking them at a CC for economic reasons, then you want to do two things. 1. take upper level science courses at a university to demonstrate you can handle the hard science.
2. in your application, in an addendum explain your reason for taking those classes there.
Still risky though.
Good luck.
