I don't know when your class is, but you could just invite her to get lunch with you on campus or something.
Also, getting her out with friends is the best option, however, getting her out under the pretext of hanging with other friends can work. If you can't get other people involved in a group activity, you can tell her that you are doing something with a couple of friends. When the event roles up, and you meet her, just tell her that your other friends flaked. It will be important to manage her reality, so you probably will want to say something along the lines of, "Yeah, I know what you are thinking. It looks like I made that all up just get you to hang out." Don't be apologetic, and don't move too fast if this is how it goes. However, make it fun and build Kino. I forgot about the end of the quarter and stuff. If you don't close with her before then you are SOL. Take it from a guy who knows. I lost a lot of women, because I didn't act fast enough, and we would start to click right before the end of the quarter. The next quarter, after all the vacations were over, there would be no remaining attraction, and generally, since I didn't have an excuse to see them (class) it was really hard to build it again.
One important thing about getting your friends out to do something:
Don't try to get them out to help you get a girl. What you want to do, is get them to come out and do something that you know they will enjoy, just as friends. Then you invite the girl. If it is something unusual, that is okay, because it is different. It separates you from all the other guys this girl has "dated" before.
