I attended SUNY Buffalo 1999-2003. We had online course registration - in the latter years, you could enter the courses you HAD to take, and the courses you wanted to take. It would come up with every single permutation of your schedule for you. You could also black out times that you didn't want to take any classes.
Manually, this was atleast a 2 hour ordeal for me to figure out the best class/work schedule. Using this tool, I could sort through 50+ permutations in 5 minutes, pick out my favorites, and had my schedule nailed down in 10 minutes max.
2 Hour savings X every single student X twice a year = you look like a hero.
