What is a day worth?

I have been doing a lot of self study this semester. At the beginning of the year we were given books to take home. As the year has progressed, there have been only a few assignments required. The teachers lectured for the first four weeks and then stopped. I guess they got tired, or ran out of things to say. The remaining fourteen weeks, a teacher will stick his head in the class long enough to take attendance and then 'pop' their gone again. I have learned plenty of socialization skills and became quite educated in movies and music. CRAM TIME! Major crunch. This week is finals. I feel I have had to learn an entire semester of material on my own in order to pass the district exams. The questions on the exams seem to be related to the text books, which I'm thankful I read. However, if on the first day of school they just gave us our books and told us to go home and read them. We could return the week of finals and take our exams. What is a day worth to you?...but that's High School.
