Take Physics 2 after taking Physics B already?

My son took Physics B last year already before the change. Is there any point taking Physics 2 next year since his school doesn’t offer Physics C?

None whatsoever. He already learned E&M, sound, and light from AP Physics B. Additionally, no college will grant credit for both. He’s better served looking for an online Physics C option, community college option, or another subject at his HS.
