Homeroom Teacher Is Important

I would never forget one thing when I was in high school. My chemistry course was not good at that time, generally scored around point 60( full is 100).
But at one unit testing, I scored 90, ranked first 5 in my class.
At that time, teacher usually ask the first 10 ranking students queue to step onto the class platform to get their exam paper.
My teacher said there was maybe somebody cheating on this test, so he got a better result, that was a shame.
I thought the teacher was setting me up, I felt upset and hated this teacher much.
Of course , I totally lost interest of learning chemistry.
