My university actually had a bidding system. You would start the year with 10,000 points, and you could bid any number on electives. So you could spend a lot of points on one particular popular elective, and be guaranteed to get it, but then you would not be able to bid as high on other electives for the rest of the year.
The system was pretty smart, except for the part that you could bid negative amount of points on an elective that wasn't particularly popular and increase your total. That was a pretty major flaw.
[edit: I should say that I didn't use my extra points for anything. I wasn't particularly interested in the popular electives anyway. I did make sure to end the year with 10,001 points, hoping they would fix the bug, but I don't think they did.]
