I am writing multiple choice paper in following format

\documentclass{exam}

\begin{document}

\begin{questions}

\question This is a multiple choice question
\begin{choices}
   \choice this is a choice
   \choice this is another choice
   \CorrectChoice this is the correct choice
   \choice this is another choice
\end{choices}

\end{questions}

\end{document}

and I want keys to display at the end of document in table but couldn't get. Kindly help.

I didn't find any way to do this in the manual for the exam class, so I made a quick custom solution that prints a list of answers automatically. The only thing that you must do is to use \CC for the correct choice, and then write \printmyanswers to display the answers as a list. There are some examples on this site for the tabular, but it's pretty verbose and I'm not sure it's worth it.

I put the answers in the same page, but you can simply add a \newpage before the command, for example.

Output

enter image description here

Code

\documentclass{exam}
\usepackage{pgffor}

\newcounter{solcount}
\setcounter{solcount}{1}
\newcommand\CC{%
    \CorrectChoice\label{sol:\arabic{solcount}}
    \stepcounter{solcount}
}

\newcommand\printmyanswers{%
\section*{\centering Answers Sheet}
    \foreach \x in {1,...,\thequestion}{%
    \noindent
        \x.~\ref{sol:\x}\par
    }
}

\begin{document}\noindent
\begin{questions}

\question This is a multiple choice question
\begin{choices}
   \choice this is a choice
   \choice this is another choice
   \CC this is the correct choice
   \choice this is another choice
\end{choices}

\question This is a multiple choice question
\begin{choices}
   \choice this is a choice
   \CC this is the correct choice
   \choice this is another choice
   \choice this is another choice
\end{choices}
\end{questions}

\printmyanswers
\end{document}

  • The problem with this code is that the \CC options appears in a more darker font color, hence students will easily tell that it's the intended answer

  • @Freeman Did you verify this by printing the page? PDF viewers are not 100% reliable as they create artefacts at times. Also, the font I used is black, so what you say is highly unlikely to say the least as there is no darker color than black.

  • i will print it later on, however the other challenge i am encountering is that it only prints four answers. However i really like the code as i do not need to manually write answers. It is really really good, except for those two

  • @Freeman Sorry, not sure I understand. Are you referring to the multiple choice answers? Or the solutions? I'm asking so I can test your situation.

  • The solutions. I only managed to compile only four solutions, with 13 questions.
