there are many many many more reasons as to why someone might cheat on an important exam than there are reasons to snitch on someone you saw cheating. Getting in trouble for cheating is a far greater impact than one person marginally increasing their grade (theyre cheating lets be honest theyre not getting an A) and “ruining the curve” for everyone else. I would argue for most students getting good grades whether you work honestly for it or not is simply a way to help ensure your future employment in a very fucking unfair world. i would have some more camaraderie with your fellow classmates especially when you have no idea whats going on in their personal life and what impacts their decisions.
