Ask HN: College starts Monday. Any software to optimize my class schedule?

About a year or so ago, I wrote that I would be returning to college to complete my CS degree, after dropping out from a different college in 2006 after my first year:

Due to some bureaucratic snafus, I only got my electronic acceptance letter yesterday, with classes starting on Monday; but hey, c'est la vie.

As I said in the post I linked to, I've become much more strategic about life. I want to optimize my college schedule so I can make the most efficient use of my time. The university has published a list of available timeslots for the classes I'll be taking. Is there any software that allows me to input the subjects, and available times, and then have it solve for things like "early classes where possible, no classes after X PM, available free days, etc.?

Help a hacker out!

PS. Feel free to throw in any college tips :)
