How to flirt with a guy in my college class?

Anonymous
Okay, so there's this guy in my class that I have a huge crush on. We had a class together last semester once a week, so my crush never really went anywhere. Now this semester, we have a class together and then walk across campus where we both have a class (we're in different classes though). I have been in this new class twice now, and we talk a lot-- laughing at the professor and talking about the class. I just don't want to be seen as a friend (he is a year older than me too). He sits in front of me and we make eye contact when we find something funny or annoying. How and when should I flirt with him? I don't like many guys, I don't want to miss this chance! Thanks!
