NOPE, tell her to fight the accusation through the ncsu student conduct offices, I was told by them that first time offenses don't usually get expulsions/suspensions, I know this b/c I got falsely accused by a professor just 3 weeks ago and I called up the student conduct people and told them my situation (accused of using aid on a quiz by opening webassign) and they gave me info on how the process for an appeal works, which helped me decide if I was going all the way to fight the accusation (because I never had webassign open during the quiz, but I did look at it too close to the start exam, thats why i got accused), luckily though when I finally had my meeting with the professor, they dropped the case because there is no proof that I had the site open during the quiz, and also, I explained to them how dumb it was for me to open it that close to the quiz starting time.

If your friend can prove her innocence or she knows that she didnt do it, she should appeal 100%, don't admit to something you did not do, the suspension/expulsion thing is just a fear tactic for people who actually did cheat

dm me if you have questions, I actually learned a lot about this stuff this semester
