Am i right or is she?

Ok so my friend asked me to do her math I said yea bc I wasn't planning on going to her house but i did. I was talking with her mom and she didn't even remind me of the work she went to her boyfriend and was like "I had someone to do it but doesn't look like they going to do it." I told her I'd do it but come sit in the kitchen with me so I can explain it to her. She wouldn't. She said that she doesn't need or want to learn it. She has a D in this class. This shit will be on our exams if she don't know it she fails. I care about her I don't want her failing. Doing her work isn't going to help her. I tutor kids so I know how to get them to remember stuff and she said that if our friend don't know this and is graduating 2 years early don't know it she doesn't have too. She said that girl is smarter then me. No that girl took a test that I was not offered and cost to take and oh yea I'm pregnant and have to leave 2nd semester. She saying I'm a bitch and ditched her all because I wanted to teach her how to do it.
