Why do I have to take Classical Physics at UCI?

I have credit for Ap Physics C: mechanics because I scored a 5 on the Ap exam. But why must I take classical physics when the subject material isn’t new and pretty much exactly the same: momentum, force, torque, etc. Mechanics wasn’t much of a challenge, and sitting in a class where someone talks about something you already know seems very boring and like a waste of time.

This is UCI’s AP Credit policy for AP Physics.

Physics 1: Score of 3, 4 or 5 earns 8 units elective credit.
Physics 2: Score of 3, 4 or 5 earns 8 units elective credit.
Physics B: Score of 3, 4 or 5 earns 8 units elective credit (not offered after 5/13).
Physics C (Part I or II): Score of 3 earns 4 units elective credit; score of 4 earns 4 units subject credit for Physics 2.
Physics C (Mechanics): Score of 5 earns 4 units subject credit for Physics 2 and 3A.
Physics C (Electricity and Magnetism): Score of 5 earns 4 units subject credit for Physics 2 and 3B.
