Something that works for me. And works everywhere in every situation.

People like being caught off guard if it's a pleasant experience.
People want mystery and excitement. So going up saying "hi my name is, what's yours?" And then ask about the class or any other BORING, Plain, everyday thing will just say "Hi, I'm boring. who are you?"

No, what I've found to work anywhere. Street, pub, class, shopping mall. Is just find a person or a group of people you find interesting. Walk up and sit down or find an open spot. Smile and say "Hi, so what're we talking about?" Act casual, fake every bit of confidence if you don't have any, pretend that you have known these people for years and you are their best friend.

It will seem so strange, so weird and NOT normal that while some of course will go "You're in my space, get away" More will go in the lines of "..interesting, let's see where this leads" (if they end up being boring or lame you can just excuse yourself and leave. No feelings hurt)

Now since you're in school its even better. You have the same class, you will see her every class. Do NOT introduce yourself. Don't say your name even if she asks. Play with her, innocently. Don't manipulate, just have fun.

Sit down next to her when she enters the room, just say hi, stay cool and do your thing (get up books and look at the time whatever) Wait for a while, don't show any suspicious behavior. Ask her something about her self, but not like, "So what do you like?" But more.. "What's your religion?" Make it personal. Start a discussion, she'll think you're smarter than the average "Hey babe, wanna grab a cup of coffee?" guy. (No offense! This works too sometimes!) You can't be sure it won't offend her but keep in mind what you think might be a sensitive topic and stay away from those.

If she's a shallow person, she'll raise her eyebrow, do that nose thing where they look disgusted and answer "uuuh.. whatever" or something.
If so, just say "Right.." Like it was nothing. Ignore the fact that she just treated you like some loser. Pretend you're friends and act as if you do with your friends. If she makes fun of you, make fun of her and put on a cocky smile. Just keep it casual. If it doesn't work, she probably wasn't worth the effort. Just a shallow narrow minded girl.

(Not ignoring the fact that she just might not be interested in boys or social relations at the time)

After class, if all goes well. Say hi to her when you see her walking by.
If you KNOW you made a good impression on her. Don't sit next to her next time. Keep saying hi whenever you see her. But make her wonder.

Nothing ventured, nothing gained. When it's such a trivial matter like this why not just go for it instead of regret over wasted time?
