Remedial Classes
Talk with some teachers that teach those provisional classes for students who are admitted on a provisional basis because their scores weren't up to par or they didn't earn the proper credits in high school.
Sometimes these teachers will give you the credit for their class if you've passed the higher level class in the same subject.
For instance if the Freshman English is numbered 101, most schools have an English 001 for students that were admitted as conditional or provisional students.
It works much better if you are cool with the teacher but if you need an easy A for a class that's one way to go.
Gym classes are easy A's too.
Well they were for me.
