So, apparently my math teacher is perfectly just in lowering my grade from an A to a B because I wasn't trying as hard as the other students for my grade, so he lowered my " Participation grade ", which is a BS thing to grade in my opinion, as it is simply up to the teacher's discretion, pretty much allowing them to give anyone they don't like bad marks. But seriously, what am i supposed to do? stop being good at math?
