Freshman/Junior?

Just got into college and have a sport camp with a girl who happens to be 20. I’m only 18, but this girl happens to be beautiful and has an amazing personality. Very smart too. I’m friends with her friends, so we have a mutual connection, but I haven’t officially had a conversation with her. We’ve shared some words here and there, but I wasmy trying to force anything just yet until I figured out more about her. It’s been 5 days so nothing much has happened yet. Just found out today that she does have a boyfriend but they don’t seem to be too serious. I’m honestly determined to get this girl but 2 and a half year age difference, junior/freshman? Is it worth it and how would I even go about getting her. Any suggestions would be awesome (:

If she has a boyfriend, stay away. Don’t be that guy.
