I want a good grade, so I'll ask my friend who passed the test for the answers
Why are you going to ask your friend for the answers?
I want to know the answers, I've failed all my subjects in school
If you're failing you should study harder, not cheat. Maybe you could hire a tutor.
Everyone does it so I'm going to do the same.
Tests are there to assess your knowledge you learned. If you cheated on it, you'll never know how you're doing. It doesn't matter if other students are cheating or not, you shouldn't cheat.
