How can you make your crush like you?

ok.so i like this guy that is super smart(genius type)..I have him for history and science...he is always better than me.am kinda of smart(straight A student) but he is still better than me:( . he talks a lot, I think he flirts with another girl...she is smart too(not genius type, she is in my science and history class too) last week we made a test in algebra..I got a 100:)(only one in the whole school), he got a 98.. I thought that he will look at me as a smart girl(I am not really good at history and I don't talk in science class) but i think he is jealous now rather than likening me... what can I do for him to like me???
