A3 Announcement
A3 is up on the webpage and available for handout.
Midterms Out
Midterms results are in the average was above 72 percent. I think this is pretty good so there will be no curve. Marks will be uploaded to CDF shortly. See me in lecture to pick up your midterm (I’ll leave some time at the end).
