Some help?

Something similar like this once happened at my school, but it was a big exam and the kids who ストール, 盗んだ it made copies for everyone else who wanted.
They got caught and were punished along with some of the people who had access to it.
My point is, あなた should never cheat like あなた wanted to, because not only あなた would regret it and the punishment あなた would get would be even worse if someone found out.
It doesn't matter what the others think of あなた for not deciding to cheat; what matters is that あなた didn't and あなた should be proud for not going down to their level, because they might have gotten access to the answers, but that doesn't mean they will when the other one comes.
About your dad, call him and calmly explain what happened and why it happened. If he gets mad at you, explain that at least あなた did it fairly and not によって cheating.
And to make up for it, before the 次 exam comes study harder so あなた prove not only to those kids but to yourself, that あなた don't need to cheat to get good grades.

Be straight up with your dad n explain あなた were trying to do the right thing.

Just tell your dad あなた didn't want to cheat and あなた made the right choice.
Those kids are the ones who should go stick there faces in someones 尻, お尻 for making あなた think your retarded.-_-

First of all i commend あなた for not cheating. Cheating gets あなた nowhere at all and あなた should be proud of yourself.
Don't worry about what the other kids at school think, they mean nothing to you. If they can waste their life cheating, then they're not worthy of your time lovey. Don't worry about them.
As for your teacher and your father, calmly explain that yes, あなた didn't study as hard as あなた could have, あなた have learnt your lesson and when the time comes for あなた to take the real test あなた will study twice as hard to up your grades.
However, i only advise あなた on this bit as it is up to あなた - will あなた tell on the other students for cheating?
If it were me, i certainly would have done. I'm that kind of person. However あなた have to think of the consequences to tattle-telling. Even though the students may not automatically assume あなた told, they may turn on you.
but if あなた don't tell on them, and your teacher finds out you've been hiding information from her/him it could come down even harder on you.
Your father will understand, surely he took exams and felt pressurised. あなた could involve him a little also, 表示する him あなた trust him to help. Once he's gotten over the disappointment of あなた getting low grades, he'd feel so happy you're pulling your finger out and asking his help to クイズ あなた on the 回答 または explaining difficult things that he'll soon forget all about it.
Over-all just remain calm. :) i give あなた the best of luck X
