At ICO it is completely student run. If you want to receive notes, it is about $75-100 per quarter. It all depends on how many hours there are to take notes on. The student who take the notes make bout $30/lecture. Most only do a lecture or 2 per week. It is not as much a transcribed lecture, as just notes on it. They usually put in everything the prof says, but not word-for-word. They also include pictures, graphs, or tables when appropriate.
There is a note-taker coordinator for every years class, a overall coordinator, and 2 printers per class. Every position is payed.
