Other

• Office hours Wednesday 4/17 are cancelled; let me know if you would like to make an appointment for another time

  • There will be a Week 13 checklist posted during the break; no new assignments will appear there.
• Test #3 will be given in class Monday 5/6 (Week 15)
• You should have received an email from the math department about a “reflection and support” module in WeBWorK. This is separate from your usual WeBWorK homework and will not impact your overall WeBWorK score, though it’s there to help you with the course material. When you click the link in the email and log in with the information yo were sent, it will take you to a separate WeBWorK section with three sets. Complete each of the three sets for five extra participation points (you’ll get the five extra points only if you complete all three sets).
  • The timeline for the different part of the module is as follows. As long as the activities are open, you can take as much time as you need to answer the questions. However, for Activity Demo and Activity, you have only one attempt to submit your work. To submit your work, you need to click on Grade Test after working on all problems.
