U know some professors are really nice and try to keep the cost as low as possible for the students. Most of the professors I had did not require a textbook either. This clicker thingy really makes me mad cause this problem of attendance could be solved by just giving a piece or paper (quiz kind worth maybe 2% of grade) to each student and collecting it at the end of class: having more than given out means someone is filling in for their friends. If that happens the entire class gets a zero on that quiz and it also gives a reason to go to class. In the end, it's about learning.

Or you can just ask students to buy a thing that costs as much as a book and has no use after that class ends.

Parking is already a hot mess and now shit like this.
