another funny thing about grading. Frequently they have to start students as lower to make them improve. If you started everything high and they stayed the same that would imply they learned nothing, right? So that is the dilemma of teachers (which I find ridiculous). Ironically same thing happened to me in my job when I was rated by my supervisor working in schools. I had to laugh as they explained to me that even though I was doing great in every area they had to give me 3's so that I could progress to 4's over the first couple years. They have to show growth smile
