Please remember that there is no extra credit in this course, and that you earn your grade, equally divided (20% each) across three exams, weekly homework, and the stock market assignment (see syllabus). I'd like to ask the very few who do, to refrain from asking for a grade change, or a grade that you did not earn. Read about self-serving bias. Of course, if you think there has been a grade calculation error, do let me know! Thanks, all! Be well. :)
