I was in year 11 when my friend helped me cheat on my exam.
Did you ask your friend to help you cheat?
No, but I was stupid enough to try to copy from her, and I think she let it happen.
Cheating is always wrong, even if you didn't ask for help to cheat. Allowing yourself to fall into that trap was dishonest, and if you were caught, it could have gotten you expelled.  Your friend could also have gotten into trouble.
It was only one question, and it doesn't matter since I'm not going to go to uni.
Even so, I still have to assert that it is wrong to cheat, even when the stakes are relatively low.  You could have gotten into trouble at school, even if you had no plans to go onto university, and this could even have affected your job prospects.
