If a student tells a professor someone was cheating, what happens?

So I have quizzes every week. There is this girl who sometimes will ask me for the answers. I never give them to her. I had my phone out today and she looked at me like put it away. She looked evil. Like she will tell my professor i cheated on the exam. I’m not even doing well in the class. I have only done well on one exam. The rest has been poor. I’m afraid she will tell the professor something. She is constantly asking me about my grades and it’s weird

If you didn’t cheat you have nothing to worry about. Move your seat so you no longer have to sit near her.

If you didn’t cheat don’t worry.

Keep your phone out of sight for future exams.
Let the person know you don’t discuss test grades.
Move away from her if possible.

She is always asking me about how I do. I have another class with her and she always comes to me first. Doesn’t ask anyone else. In one class she sits across from me and use to look at me and ask me for answers. I would not tell her. I didn’t know the answers myself. I still wouldn’t tell her. I feel like she would be out for revenge this time
To be petty

It’s pretty easy to tell if she’s cheating off you. Especially if you’re not doing well.

I wouldn’t sweat it.

I don’t have any advice but just FYI never take your phone out during a quiz/test/whatever. I thought that was just common sense.
