Document Classes ⇒ trying out examdesign...

[mathfeel]

I am looking for a class that help me generates randomized multiple choice quizzes. The only one I found to claim such capability is examdesign. I am following the manual to create the following minimal tex (mostly copy-and-pasted from manual.pdf):

Code: Select all

\documentclass{examdesign}
\begin{document}
\begin{multiplechoice}
  \begin{question}
    How much wood could a woodchuck chuck if a woodchuck could chuck wood?
    \choice{A lot.}
    \choice{More than most.}
    \choice{Exactly $\pi$ cords.}
    \choice[!]{It depends on the nature of the woodchuck.}
  \end{question}
\end{multiplechoice}
\end{document}

It compiles but with error:

Code: Select all

Is anyone familiar with this class or the error?

Also this class do not seems to scramble the choices of a multiple choice question. Do anyone have a good class recommendation for this purpose?

[EDIT]: After an unnecessarily long struggle, apparently certain macro like \class must be defined. So at least latex does not spit any more error.
