If he ever does a class presentation and focuses mostly on you. He likes you hands down. It's been proven. However!! do not fool your self into thinking that he likes you
It's possible, however there are certain things that you can do to make him more intrested. That being said, you can't "make" someone like you. What I would do if I were you is just be nice to the guys you are interested in! Talk about school or things you might have in common. You should smile though, I bet you have a beautiful smile. Smile in a way that is not so fake though. What I find REALLY helps is the first glance you give someone. The first conversation, first impression on someone first anything. Try to look your best, smile and act in a naturally playful way. You will have them captivated. Just give them a little bit. Confidence is huge as well, you can do it hunny I know you can! :)
