Extra Discussion Points!

Due Date:  Reading Day, 13 December 2018!

To help you prepare for your final exam, and reward all of your hard work in discussion, we will add your PrairieLearn Review Assignment scores to your quiz score. Here's how it will work:

  1. Your review assignment scores will be averaged together.
  2. The result will be uploaded to the grade book as Quiz 11.
  3. We will increase the number of dropped quizzes from 1 to 2.

You will have one opportunity to have your review assignment instances reset according to the following schedule.  Remember, if your instance is reset, all of your previous scores will be erased and you will be starting over.

Use the links below to request a reset.
