While I would agree that most of the time using the excuse that the teacher doesnt like you , seems silly, It isnt always. In my case, I had two teachers who didnt like me. One I think didnt like males, but not sure. In high school, I always took Honors English (including AP English) and always wound up with a A or B+. One semester, I had to take regulard English class and wound up with a C. The next semester I took Honors English again and wound up with an A. I did notice that none of the other males in the class ever scored very high with C being that higest grade in the class (yes i asked) I doubt it was on purpose and I actually mentioned it to the teacher who responded that while she had nothing against the male students she did agree that none of them scored very high in the class. Who knows what happened. Next teacher was in Spanish. Now I am Argentinian so I think she thought I was cocky (which I may have been) In my school you got three grades, one was the actual class, the other was for effort and the third was for whatever. The best grade was AEE (e for excellant.) I wound up geting a AUS (u for unsatifacotry and S for satifactory) She set me aside to tell me that she didnt like how i acted in her class. Now, i was always a goody two shoes throughout school, so i never understood what she meant. I wanted to tell her I would have like a AUU, which basically means i got an A in the class, put no effort in and wasnt a good student. Didnt have the guts to do so. Last was my son. He went to a Jewish day school and didnt really like studying Hebrew and Judaic studies and honestly put no effort in those classes.. He had a Hebrew teacher who we were informed (dont remember by who) that she was going to break my son which she didnt. Overall he did very well in school, but they didnt appreciate his attitude in those classes. They did wind up getting the last laugh. They took a portion of the class to Israel (those who wanted to go and were accepted) and when my wife applied for him, they turned him down because they were afraid that he wouldnt behave. That came from his Hebrew teacher
