Most Helpful Guy
Many guys don't.. but many guys do. Very intelligent/hard-working women are empowered, generally confident and independent. They have strong career prospects and don't need a guy for financial stability. Guys can find that very intimidating (and feel like they aren't 'needed') - just as women can find large, strong men intimidating. Sounds like you're just meeting guys who intellectually aren't on your level at all. Don't settle if the brains don't match for sure. Class? Library? Maybe guys where you're studying?

Who cares if a guy likes / dislikes the fact that you're studious?
Be studious. Be studious all day. Be so studious that you're leagues smarter than all the guys who would be turned off by such an awesome trait. You'll find someone who's worth your time.
