Is my friend being clingy or i'm just being a badass friend?

lately, my friend seems to annoy me. she always ask to copy assignments from me and it also goes the same with projects. not that i don't want to share it with her but it's like, she would text me several times a day to ask for that. it bugs me. also even if i don't have class (we have different schedules), she would ask me to go to school. i don't know why, and i don't go. i was thinking of stop hanging around with her but that wouldn't be a good idea because some of our friends might notice and they would think something is going on (which is actually true). am i just being grumpy and overreacting? btw, we're in college.
