When exactly does the orientation end?

@PhantomVirgo my CC was on a quarter system, and I finished MATH 1A, 1B, and 1C … equivalent to MATH 21A, 21B, and 21C at davis…so I can successfully register in PHYS 9B, but I’ll ask my orientation leader just in case. Do most people with AP credits, just skip PHYS 9A? or do they start over?
