Well I wasn't exactly worried about it...I ended up passing one class in 5 years. Most I failed for attendance (I only showed up for tests, labs, or if we were going over something I wasn't comfortable with (which was almost never). The rest were failed from lack of homework (I never did more than 1 assignment from any particular learning segment), attitude, or political grievance (yes I failed 3 classes over policies (like religious, ethical, and such)). I also failed 2 semesters due to suspensions and expulsions (once for fighting, a few for absences, a couple for political stands, a couple for weapons, some other stuff I don't remember).
Interestingly my college GPA has stayed between 2.15 and 3.35, and I still do the exact same things with the same attitude and philosophies. I guess it goes to show that school is more about politics than learning.
