Just a rant for then so...... I am 20 M and she's 20F

Hi everyone. Writing because I have no one to talk about this, just want to clear my head. She called me today for the exam we have tomorrow. Like she haven't prepared for the exam. When I tried to help to like what to do and stuff, she was like that wasn't she wanted. The tone went low and I felt what I did. She's form another college and we often talk to each other. am like what did she expected?
