I signed up for AP Chem in HS, because I loved math and did great in AP Physics.

It was a disaster.

The teacher was this creepy man who ignored my questions. All the students in the class had outside tutors and my mom was like "if you think you need a tutor take the regular science class" -- I could not make heads or tails of the homework. I lasted two weeks then transferred to Statistics and got teased all year for taking two math classes. (I would have cheerfully taken 3)
