How do you politly tell a teacher the work your doing is dumb?
Be honest just say there's no point for this really you want me to do this ?See what she says .
you don't, she/he will fail you
Oh!... Never do that!... Trust me you will regret that alot... Just deal with the teachers crap cone home and watch a few educational things...
Just say: This crap is pointless. *walk out* Just kidding. Just keep going and count the miserable days until you get out of the rotten hell hole.
