I'm going to convince my friend that I will copy her assignment.
Why do you want to copy the assignment from her and aren't you scared the teacher will find out?
It'll be good for my grade. I can even copy her assignment word by word. Anyway she will never find out
It is normal to want to get great grades but cheating is not the way to do it. You could get in serious trouble and so will your friend.
I don't care about the risks. I want to get great grades.
Even if you get good grades, you will not have learned anything and you would only hurt yourself in the process where you wouldn't be prepared with your chosen career. If you can, try to ask a tutoring session with her instead so that you would also socialize in the process.
