If you feel like there is a mistake with one of your grades, make sure to review your feedback on Ed first. If you still feel like there is a mistake after reviewing the rubric and comments left by your TA, then you can either email your section TA or the staff mailing list and cc your TA in the message. Make sure to explicitly state what point(s) you are arguing for and why you think you earned it. There is no guarantee that the point you lost will be awarded back, but if the staff also finds a mistake has been made, your grade may change.
Exams are graded collectively by the course staff, so individual TAs have less power to deal with exam grading issues. For exam regrades, give your exam to Stuart along with a short note describing what part of the exam you think was graded incorrectly. Keep in mind that your score can go down, so we encourage you to submit a regrade request only if you think there was a large point difference between the score you received the the score you deserved. Midterm regrade requests must be submitted by Wednesday, May 18.
