What is actually the difference in student experience between a world famous university and others?
Even if you could learn exactly the same thing in both places (you can't), another difference is your peers. If you are surrounded by people who are smarter and more driven you'll be more likely to raise your own standards. The best project in the class at Leading University will be different from the best project at Third Tier U.

Also, if you attend school with people who are likely to get great jobs, you'll have contacts with people who have great jobs, increasing your own opportunities.
