I'm thinking of trying to sleep with my teacher to get a good grade.
Why would you do such a thing?
In my mind she will give me a good grade because I am innocent and young.
You shouldn't sleep with your teachers and they shouldn't sleep with you. Don't do it or it will end badly.
But I want a good grade.
If you want a good grade then you should do it the responsible way by studying hard and doing well on the assignments.
