Loren Dill,

Will the following work for your purposes?

Needs["DiscreteMath`Combinatorica`"]
NumbofQuestions = 20;
Table[RandomPermutation[NumbofQuestions]]

work for your purposes?

Hi,

I'm a math teacher, and need to prepare exams from time to time.  I
typically prepare questions for the exam in a sequential order starting at
the beginning of the material and going to the end.  I may have something
like 20 short-answer questions.  I want a program that will randomize the
order of the questions.  In other words, I want to provide n, the number of
questions, and have the program provide a list of length n that contains all
the numbers from 1 to n in a random order without any number being repeated
or omitted.  I'm sure that this is an easy task for Mathematica, but I can't
figure out the best way to do it.
