I cheated my entire way through the school year
Why did you cheat so much?
I was bored and I wanted to make things more interesting
You can't help if you're bored in school. But cheating is wrong.
It was a challenge.
If you cheated due to boredom, you could have done fine without cheating, I would imagine. Eventually cheaters get caught, and your success will fall down around you. Better to work hard and own your successes.
