I never have cheated..I suck at keeping things hidden (such as me eyeing over my classmate's work), so I didn't bother. If I ever got caught, the teachers would've surely given me an instant 0 mark. I'm usually the person who people go to for answers though, so it's them who are at a chance of failing.
While this may not be related to tests per se, people keep asking me for help relating to studying/school work in general. I reluctantly do this, as it's basically, well let's say it like this.
it's like fixing a hole in someone else's wall, when they clearly have the materials to do it themselves. A waste of time.
