Create an environment like the checkboxes in exam.cls

I am having trouble on how will i create something like the checkboxesor oneparcheckboxes environment in exam.cls. The only difference is that since the checkboxes gives circle, i'd like to create environment which give squarebox for multiple choice.

when i type this in .tex file:

\documentclass{exam}
\begin{document}
\begin{questions}
\question How should I?
\begin{checkboxes}
\choice AA \choice BB \choice CC
\end{checkboxes}
\end{questions}
\end{document}


it would output a vertical lane of choices like

and using oneparcheckboxes environment:

 \begin{onecheckboxes}
\choice AA \choice BB \choice CC
\end{onecheckboxes}


i would like to create something like the checkboxes and oneparcheckboxes:

If using the exam class is an option, I'm sure you can redefine the symbol it uses for checkboxes. Is there a particular reason you want to avoid the class? –  Sean Allred Feb 26 '13 at 14:39

You can use \checkboxchar{$\square$}

Code:

\documentclass{exam}
\usepackage{amssymb}
\checkboxchar{$\square$}
\begin{document}
\begin{questions}
\question How should I?
\begin{checkboxes}
\choice AA \choice BB \choice CC
\end{checkboxes}

\question How should I?
\begin{oneparcheckboxes}
\choice AA \choice BB \choice CC
\end{oneparcheckboxes}
\end{questions}
\end{document}


You may also like putting \checkedchar{$\blacksquare$} in the preamble just to keep the aesthetic look.

alright, im going to try this one. I've seen this one in the commands declared : \checkedchar{$\surd$} what does this mean? especially the \surd? –  Kayla Feb 26 '13 at 14:48
@Kayla Put \checkedchar{$\surd$} in the preamble and see yourself ;-). It puts a tick mark. –  Harish Kumar Feb 26 '13 at 15:03
