i hate my economy teacher

okay so we had a test last week which was a really hard test since there was a lot of math in it. now my teacher wasnt nice from te start, he kept saying that we were all going to fail, so i obviously thought that i should study harder and i did. mind you, i really suck at economy and my teacher knows that so he always treats me like im some awful bad behaved student. then some rumours came out that my class committed fraud and had the test answers (which wasnt true) so a whole lot of drama came out of that. i unexpectedly got an average grade (6,7, which is good bc 5,5 is a bad grade in our school system and a 10 is the best) and my economy teacher just straight up shouted in the class today: you have a really unexpectedly good grade, hmmm thats suspicous did you commit the fraud? i thought you would defenitely get a bad grade....
it kind of hurt tbh, ive worked really hard on economy this year and he made me feel like i didnt deserve a good grade because my past grades werent that good, and he doubts me so much that he simply doesnt believe that i'll ever improve so he thinks i cheat or commit fraud whenever i do get a good grade.
urghhh i really just wanna prove him wrong or smack him in his face (╬￣皿￣)凸
