Do grades reflect students who is trying hard in the class?

Not necessarily. Grades can be considered a measure of a result, it would depends a lot of the result you are measuring. For example, if you measure the behaviour of interest in class, the student that is trying hard in class would score well. But it also can happen that when that student face a test get blocked and stressed and do not score that well. Grades will always depend on what is measured, and currently those measures will be strictly connected with the beliefs of the teacher and his understanding of the most effective way of teaching.

cornelia

explanation:

we don't know all that much about cornelia aside from what granny tells us about her, along with what we can gather from her few lines of dialogue. it's hard to picture her, too, since we're not given any details about her mannerisms or what she looks like. she could be dressed like a circus clown, for all we know.

even though we wouldn't recognize cornelia if we ran into her on the street, we can't but feel a lot of sympathy for this character. first of all, she's super nice and granny pretty much treats her like dirt. she's constantly asking granny if she needs anything and granny usually responds by snapping at her. here's a typical exchange:

"i thought you might want something."

"i do. i want a lot of things. first off, go away and don't whisper." (14-15)
