Announcements

  • Test 2 is Friday
    Test 2 notes are posted
    I am collecting solutions from you for practice test problems for posting on the website by Wednesday's class. I will award 5 HW points per problem for every solution that I post.
  • Final Exam will be Saturday, April 26th from 1-4 PM. Please let me know ASAP outside of class if you have a conflict at that time.
  • Each group is responsible for getting extra copies of handouts for missing group members.
