I cheated on my SAT and ACT. No one found out.
Why did you cheat on your SAT and ACT?
I wanted to get a higher score
You shouldn't cheat on your SAT and ACT just to get a higher score. If the school finds out you could be expelled.
I'll be careful and not get caught.
Someone could eventually find out and you will be in trouble. Teachers can reverse the grade if they find any suspicious behavior.
