I'm going to try to change my grade
What are you going to do to try to change it?
I'm sitting on the same side of the room as the teacher.
I see that you are motivated to improve your grade. That's good, but make sure that you don't cheat to improve it. Do your homework, study hard, and get extra help if you need it instead.
I asked the teacher for help.
That's a great strategy! I'm glad to hear you are trying to be closer to the teacher to get help, not to cheat.
