I'm in high school right now and I agree with this a lot. It's not as much in high school, but in middle school, almost every assignment had an effort mark, and it always annoyed. I mean, how are they going to know how much effort I put in it? They could look at the quality of the final product, but a few times, I would screw up completely so I had to redo the whole thing and then what I handed in would not look as good. Obviously, there was some merit to the idea having an effort mark, as that would reward hard work, but it annoyed me personally.
