What's the Toughest High School Course You Passed?

[August_West]

Adult Christian Life (I went to a private, Catholic HS).

I had already decided I wasn’t a Christian, I was certainly in no way an adult, and the teacher and I didn’t see eye-to-eye on anything. He was determined to make the class as difficult for me as he could.

I failed, but it turns out my HS couldn’t refuse you a diploma for failing a religion class. I had to do “school service work” that summer (painting lockers, mostly) to “pass” the course

For me, it would have to be a tie between Personal Finance (a graduation requirement that I ended up taking in two separate semesters to get the full credit) and Geometry. Not because the material was challenging but exactly the opposite: I struggled mightily to not doze off.
