The three pillars of wealth are real estate, your own business and investments. Not knowing to much about your situation I would assume as a college student you are not working full time so I wouldn't go for real estate.
If you are working and you received income this year that is taxable look at opening an IRA the 2k will be tax deductible and you will begin your savings for retirement.
If you are not working and you are looking to start your own business or flip the money relatively quickly look at investing in some goods you can resell at the college. Da Don has some excellent posts on drop shippers and wholesale merchandise. You could buy some ipods, psp etc. wholesale and sell at your school for the Christmas season. Try to find whats going to be hot this christmas and in high demand you should be able to make a quick flip if you invest in the right item.
If not look at what interests you figure out what product or service you know more about then the average person (comparitive advantage) and base your business off that. College is the best time to start your own business your acess to information, customers and potential business partners is huge while in school. Don't miss out on any opportunities.
