It was easy to get a good grade on the test because I took the answer sheet.
How did you get a hold of the answer sheet?
I mingled and got to know a girl and we decide to take the answer sheet together.
You are a cheater and you do not deserve a good grade on the test or in the class. You need to take more responsibility for your grades and spend more time studying so you actually know the material.
It was real easy. We only had a short time to go to the bathroom.
It doesn't matter how easy or difficult it is to cheat, what you did was wrong. When you cheat on a test, you're only cheating yourself because you're getting credit for something you didn't do. You should turn yourself in to the teacher and hope that they will appreciate your honesty and let you do something to make up the exam.
