Help meee

I (15f) have a crush on a guy (15m) and I don't know if he likes me. He doesn't seem like the kind of person to say yes, but I have 2 classes with him and sometimes talk to him. No one except my best friend knows and I'm unsure what to do. We talk a lot but I usually make the first move and blow it by being too bold and scaring them. I am pretty attractive and know I can get a guy, but I'm a bit weird and don't want to scare him off. What do I do?!?
