Wait, you want “More room for mistakes on tests” but still want an A? Not an A- , but an A, because you want “room for mistakes?”
And this is about a spiteful professor, and not your own tendency to make mistakes on tests?
And “the students in (your) school are very smart”-- it’s “Big Ten school.” But you still expect to make those mistakes and get an A, not an A-???
And you’re a smart kid, and you don’t see the holes in this logic?
Go back and read what you’ve posted in this thread. Every single post talks about the mistakes you make, and how you should get an A. (Well, aside from the one where you took out your frustrations via email… that really, REALLY doesn’t speak well to your maturity level, or your prospects for a good letter. Question: Do you honestly think she won’t share that email with her colleagues???)
I don’t think your grades are a problem. I see a big, glaring, huge lack of maturity being your main issue.
