I had to do all the homework because I constantly missed class, so I had to keep my marks up somehow. A combination of just skipping and trouble at home meant that I missed a lot, so I was constantly doing catch-up work and asking for extensions on things.
I still somehow made honour roll pretty consistently.
College was different, because I dropped the boy I skipped with, and wasn't at home. I had a different problem then, but that probably helped my marks more than anything. Life drama = expressive artwork = good marks in art school.
