If I retook the same course at a different CCC does the original grade still count in my GPA calculation?
you can only repeat courses for which you originally earned a C- or lower. When you repeat and do better the new grade replaces the old. You don’t need to repeat the class at the same college, they will still replace the grade.
See pg 30 of University of California Counselors
If I retook a class a class and got an A after failing the first attempt, would this negatively impact me in the admissions process or would it be considered the same as getting an A the first time?
It’s certainly going to look better.
