Well that would have been boring! How about a BS in four-five years with a bunch of random cool-sounding classes in between, along with a fair share of partying and establishing hopefully enduring friendships and romantic relationships.
Or you could graduate, and do the same thing, except making $10k+ a month while you are doing it. The idea that college is now about romance and partying is part of what's skewing the prices.
It's also possible that Stanford might not be the best place for you if you are unable to get grants/scholarships, and it places too great of a financial burden. You can have a successful career with degrees from other universities as well.
