That is why the NSF REU program is perfect for you. Many college undergraduates have no idea what it means to actually do research in a specific field or what physicists, mathematicians, chemists etc…do all day. REU’s allow you to get a taste. In most cases REU students are given a stipend and living expenses are covered. REUs can be anywhere from 1 week to the entire summer. There are REUs in computer related fields and physics and medicine and many other fields. Check it out:
