The best way to relieve the stress of studying for exams is to organize a massive flash mob rave party at your college and get everyone to go crazy. It relieves the stress and perhaps makes graduating a little more fun.
This video above is from the second flash rave at the College of Charleston. They organized in only 30 hours advance via the amazing connecting tool that is Facebook.
It looks like good fun and gets really messy towards the end. You can even download the electro dj mix from the rave here
