  • Extension request emails must have the words "WebAssign Extension" in the subject line. Also, the only thing, besides the request for extension, that should be in an extension request is a request for more submissions.
  • SCALE-UP Physics 2 enrollment will be limited to members of this class for the month of November by department permission. To get your personal permission number, please email your request to me. The course will be opened up without permission required in December if there are still seats available. I am taking a waiting list for students who have not had SCALE-UP Physics 1.
