Examlet 0 (Aug. 31, 2022 - Sept. 2, 2022)

As you may have seen in our class policies, our "examlets" will take place in a computer-based testing facility ("CBTF") in Grainger Library.

You must schedule your test appointment with the Computer-Based Testing Facility at this link.

Find out more about the testing facility, such as:

  • where it is
  • when to show up
  • what to bring (and not to bring)

The exam will be 50 minutes in length, and it will cover the material of the first two lectures, plus linear algebra basics and Python coding basics.

Once you arrive at the CBTF, navigate to https://relate.cs.illinois.edu, sign in, and click on the CS450 examlet. When told to do so by the proctor, you may begin working. Good luck!
