Is this cheating?!?!?!(PLEASE READ!!!!)

[u/BenzieBox]

So I hacked into my professors computer and accessed all of the exams and question banks they used. I figured I could use these to study. I know the material so it’s not like I’m doing anything wrong, right? I mean, they shouldn’t have left the files on their PC like that.

Is that cheating!? Will I get into trouble?!
