Your ITT "clicker" for the instant response of multiple choice questions has a "number" (in the battery compartment). You need to make sure that this "number" is registered to "your name". The links below allow you to do so. In this way, proper credit for responses will be assigned to you and not left as a number.

Please make sure to register your clicker for the proper class, Phys 121A (the 1:30 pm lecture) or Phys 121B (the 2:30 pm lecture). I'll check every once in a while to make sure that you are in the "right" class.

Where it says "name", please try to write your last name first, for example

Vilches, O., or Lee, H. Y., or Carranza, E, or Park, D, or whatever UW has registered you for your last name. It makes much easier to check on possible errors than searching for your first name or nickname.
