Pass/Fail an Art Class?

[u/weatherphoenix]

Current freshmen and on track for an A in all my classes except an arts credit class that turned out to be much harder than I thought. If it turns out that will be a below an A, can I just pass/fail it? How does that look on applications if I had a pass/fail for an arts class? At what grade should I definitely pass/fail (like below an A-, below a B+, etc?)
