If you're ruling out clubs/bars and university groups/organizations, then that pretty much leaves your classes and connections with friends/social gatherings that aren't at clubs/bars. I'm a little uncertain as to how close you are with your friends, but why not ask them to introduce you to single men they know at the university? If you don't have any friends at your university, do you know anyone in your classes, male or female? I agree that approaching male classmates can seem awkward, so you could start off by sitting near some men and casually striking up conversations, or you could talk to the men who partner up with for group projects. For the female classmates, you can start to develop friendships with them, and in time, ask them to introduce you to their single male friends. It's not going to happen overnight, but you can certainly start to work toward your goal now. =)
