I really tried my hardest in my class. I got an A in my first quarter, but my professor became twice as difficult the second semester, which made my final grade a 76% (C). It's really frustrating because I worked my butt off while another student cheated off of another student during all of the tests, which she made a B+.
Is my C in chemistry okay? Most of my class made C's, so I don't think I did horribly compared to my classmates.
Also, should I mention the cheater to my professor?
