Answers in table at the end of document in exam template

Question

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.

Answer 1

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

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}

Answer 2

To remove bold correct choices

\CorrectChoiceEmphasis{}

To remove the bolded answer when printing the answer key. More information can be found here here: http://mirrors.ctan.org/macros/latex/contrib/exam/examdoc.pdf
