So far, I've never been got by this particular bug-a-boo. I don't play favorites...I will give an A to a student who works to make my life miserable and will fail a friend who is in my class. I give students the grade they earn, not the grade I WISH they had earned. ;o) If you have any questions about a grade that you got, please check with me before assuming the worst. I am human...and if I get interupted in a stack of grading, or if you're comparing the first few papers of a stack I graded to the last few, there may be some differences. Point out my errors to me, and I'll fix 'em. Don't worry about possibly making a friend's score lower (such as if I failed to count something wrong on their paper, but did on yours). I won't do that, it causes too much friction in the class and can interfere with the learning of other students, too! It's perfectly possible to ask lots of questions of me and be very involved in lab and get a bad grade if you do poorly on tests and homeworks, but it's equally possible to sit in class and not ask questions or say anything, just do it and leave, and get an A. Grades are very independent and performance-based.
