I would take this in senior year if it’s just AP Physics 1. It does not require a lot of math. It’s a very challenging course (lowest % of 5s) because it is abstract, but once you get the idea, it’s fairly easy. If it’s Physics 1 and Physics 2 combined, I would reconsider because that’s too much for a person already taking 7-8 APs and needing time to write application essays.
