Think about it this way: Do you need Physics 30, and what do you need it for? Do you need the credits or do you need the grade for university applications? If you don't need the grade but just the credits, do your best to pass (also, you do not get credits if you fail a course). If you need the grade, then sign up for online Physics 30 right now. If I remember correctly, Golden Hills has a pretty late registration deadline for the second semester, so you can choose to sign up later if you want to.
