I took 2 english classes in grade 12. In the literary english class (basically the one for smart kids) my teacher was brilliant, and an incredibly nice lady. She knew the course she had to teach was stupid, and she knew I was smarter than that. She allowed me to skip every class as long as I could prove to her that I knew what was going on. She was awesome to me.
My other english teacher was for a mandatory english class. Instead of making us read classic books that disagreed with her views, she made us read garbage with a grade 7 reading level. Ironically, one of the books that was supposed to be examined in this class was Fahrenheit 451. So, when she told us we were going to be reading a stupid book by a no name author about a girl having highschool problems (yeah fucking right) I brought in my copy of Fahrenheit 451 and read it every class. When the time came for a book report, I wrote it on my book, not hers. She tried to fail me, not just on that, but on every project for the rest of the semester.
When we got our final grades, my first english mark was a 95%, my second was a 12%. I took this mark to my first teacher, the smarter one, she laughed. She helped me bring it up with my principal and we got the other crazy ***** teacher canned. It was just awesome.
Also, although my teachers never did anything other than encourage me, I was reading at a university level in grade 4, simply because I love books. It made me very sad to see my moron classmates amazed at how I could read 'chapter books.'
