Re: They cheated on the exam and it’s just not fair… should I tell prof?
Plagiarism is basically impossible to get away with nowadays. Every somewhat respected institute has a plagiarism detector. So that they will find out anyways.
I still want to know in what sort of institue OP studies, because of the easiness of resheduling tests.
As for passing forward questions, as I said earlier, that is not illegal. Unless they made you sign a paper saying ‘thou shall not talk about exam questions’.
Exams are held on the same time for every student for this reason exactly, that it makes it impossible for students to help each other with questions.
If you miss it you get a chance at resits, which again are held on the same time for everyone, for the very same reason.
In OP’s case, it makes no sense to report the person. And neither do I understand why OP is suffering from this.
