Easiest graded RA credits

[evanmonast]

I've mentioned in another thread that I want to go to law school and am looking to raise my GPA. I have stopped one class shy of graduating from UMPI because law schools only look at your credits earned BEFORE your FIRST undergraduate degree is conferred. They do not care if you got a second undergrad or a masters they ONLY care about your first undergrad gpa. 

At this point I feel as if I have soaked up all of the easier classes at UMPI and am now expanding my search to all other universities. My only criteria is that the school awards A+ grades as getting an A does not help me. I saw somewhere that ASU offeres a 1 credit course for $25, can anyone tell me if that is a P/F course or if they award a letter grade? 

Long story short I need as many A+ RA credits for hopefully as fast and cheap as possible.
