My HS CS class in 2014 was like this. It was wonderful because it took away the incarceration feeling of normal public school. If I did the work faster than everyone else correctly, I could go and do what I wanted in the school, which motivated other students to finish and motivated me to finish first. I wish other classes were like that.

The only thing close in college was profs who would let you test out of classes, and work on a self study project for the class, I loved that.
