Why don't guys talk to me in school?

Okay so I'm a junior in a high school that I've only been at for a year and I swear no guys talk to me. Like ever. At my old school, I had a couple of guy friends and boy friends but our friendships started through other people. I'm not the prettiest girl, in the world, but I've been told that I'm the opposite of ugly. The only thing is I'm smart - never had a B in my life kinda smart. But that doesn't seem like any reason not to talk to me. Even when I start convos with them it's just small talk. I don't always even want a date/boyfriend just guy friends. What am I doing wrong?
