It’s good that you realize that cheating is not the way. Talk to the teacher. Just say that you wanted to talk and apologize. Most people are reasonable and they like their students.
Change your name if it is similar to your real one.
I will tell you another reason for which you should not cheat. If a college does not take you because of a lower grade somewhere, maybe it’s your luck. Not being good enough, yet being in a cutthroat environment drives people mad. There is always a way to restart.
I taught in college too, in Europe. In Europe, we grade the students harshly, but we do not use the grades for entering university. We have exams for the really good places; the other ones are open for free. Grades should tell students what they are good at and help them choose their speciality/major wisely.
I am shocked by the amount of pressure that’s put on US kids and I hope that most of them do not crack under pressure by cheating or doing other stupid things. She needs to understand that what she did was wrong, nothing more.
