Ok me and my friend were checking answers that she didn't get and this kid accused us of cheating hes done this before, hes like im gonna tell the teacher i said synich, he didnt tell the teacher and my friend actually was copying down answers that she didnt get.
Your friend was cheating. It doesn't matter if you didn't understand the questions, she needs to do her own work. So many times kids think they are helping their friends by giving them the answers. That does not help! Explain how to do it instead.
There is no doubt, unless the teacher has given permission to share answers, that this is cheating. Please check your school's policy on academic dishonesty. Some schools fail both students-the one who provided the answers and the one who copied them-on the assignment in question. In the case of cheating in college, many colleges fail the student for the course, and there is no refund for lost tuition.
I agree that simply correcting answers from your paper to get them right is cheating. I'm sure you think you're doing your friend a favor, but in fact you're helping your friend be kind of lazy and dependent on you. Perhaps a way to be more helpful is to find the questions your friend missed and help work through them until your friend understands. The goal should be learning, not just good grades. As long as your friend knows you'll keep "fixing" the assignments, she is unlikely to work as hard to get the correct answers herself.
When your friend copies answers that she did not get herself, she is cheating. I do not know that I would tell on you if I were that other kid (probably not because it's not really his business) but that does not mean that what your friend is doing is right.
Cheating, to me, is whenever you do not do your own work. If you copy ones you didn't get, you are not doing your own work. To me, the best thing to do if you do not understand part of your homework is to go to the teacher. Ask for help. That way, you actually come to understand the answer (hopefully) rather than just copying it so you don't get a bad grade.
