Having some trouble with my connection...

Hullo! I'm having problems with my internet connection at school with my Macbook Pro and it's frustrating me greatly. My connection at home is fine, but at my college I am often unable to keep a good connection for more than a few minutes, even when other laptops seem to have no trouble. Very rarely can I keep a connection for an entire class, and this is frustrating since I use school programs like Blackboard while I work. Is there any reason for this, and any way to fix it? I'm not especially tech-savvy I'm afraid, but I'll do my best to answer any questions about further information if it can help me. Thanks!
