What I hate about School

I got an email stating that I Owe $650 and until it is paid, I will not get my diploma. What is this $650 for? This 3-week bullshit, waste of time seminar where the instructor did not do a damn thing except write a welcome post and say "thank you" for assignment submissions. This stuff makes me furious. I know, it's school, it costs money, but...ARGH!!! How the heck am I supposed to come up with $650...quicklY?
