Credit Adjustment

Make sure you call any problems with grading to our attention immediately and not later than the next class meeting after they are returned or posted on canvas. To submit a request for a review of a credit assignment on a lab assignment send an email to the instructor stating the nature of the problem and the remedy you desire. We will not consider any requests for grade adjustments that are submitted later than the one week grace period after the grades are posted on canvas. You are responsible for checking your posted grades in a timely manner.
