I was such a -blam!- off in school, I was enrolled in a "Performance based diploma program." Through some sort of unknown magic, all the classes suddenly were worth double credits. I went to proper class half day, then was bussed to a vocational school where I learned basic residential electrical wiring.
I went into my sophomore year with exactly half of a credit, (for home economics woot!),don't remember that year really at all. Spent the next two years in this program, and boom, graduated on time with the rest of my class.
