Investing Tips for College Students?

GenKreton asks: "I am a rising junior in college and decided to take out loans to cover all my costs so I could graduate with money in the bank. My tuition bill is minimal as I have a nearly full ride, but living is always expensive. With that said, I feel like my thousands sitting in the bank could be doing work for me instead of collecting dust till the day I graduate. I have been researching how I could best invest my money so I have immediate access to it if needed, but still do better than a mere savings account. There seems to be a lot of mixed advice and some obvious scams out there. So I ask Slashdot, what is the best plan for a college student to do with his money?"
