Help with building credit score

Tot

This is so not related to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, but I thought I'd get some really good advice. I'm a freshman at Temple University and I want to start building my credit score ASAP. The only way I know to go about doing this is to get a credit card, well I've been declined of every one I applied to because I don't have credit. What are some other ways that I can build my credit without using a regular bank credit card?
