Even if she does know that you like her, she might not be showing it to you because she may not have much experience with the dating thing as well. An easy way to spend some more time with her is to do your homework together for the two classes that you have. Do you have her phone number? If you do than you can call her about a school related thing. What do you have in common - movies, music, etc.? If you don't know ask her. These are things that you can easily talk over the phone about. I will agree with Nicole that it's best to be straight forward and ask her out, but I know that it’s not always easy. Good luck, and tell us if everything is OK.
