It would be useful to have a Deferred status, as well as a Not Applicable status.

The Deferred would be useful as some items may need to be addressed in future versions of a course, or in other material, but aren't explicitly Complete or Denied.

Not Applicable could be used for a variety of non-course specific, such as technical issues (firewall or browser), or comments that have nothing to do with the course, or anything about the material or technical issues reviewing the course.

I like that idea.  I know different organizations use different terms.  But if that's not feasible, at least having two more options would be very helpful so we don't have to manually change those in our downloaded versions of the course feedback.
