So you gave the exam and now you discover one of your questions had no right answer, and another had two answers that aren't really wrong. What do you do?

Shame on you! But we can help.

A detailed description of the key file is in The Key File.

This page needs to be pieced together from existing documentation, including
/physics/doc/physics/grading/grek (has info on the key file)

need to discuss:

No right answer
multiple right answers
wrong answer given


Criticisms or additions to this page should be sent to
