Customizing Multiple Choice Questions in EqExam Package

Question

I use eqexam for creating Multiple Choice Questions with randomized answers. Let's take the following example:

\documentclass{article}
\usepackage[allowrandomize,nopoints,proofing]{eqexam}%

\begin{document}

\useRandomSeed{2012}
\begin{exam}{Exam1}
\begin{problem}
In what year did Columbus sail the ocean blue?
\begin{answers}{2}
    \bChoices[random]
    \Ans0 1st random choice\eAns
    \Ans1\label{eq} 2nd (the correct) random choice\eAns
    \Ans0 3rd random choice\eAns
    \Ans0 4th random choice\eAns
    \Ans0 5th random chioce\eAns
    \eFreeze
    \Ans0 None of these\eAns
    \eChoices
\end{answers}
\end{problem}
\end{exam}

\end{document}

which produces the following output:

I want to be able to customize the problem and answers environments, more exactly, to put the problem number inside a \fbox and change the text size, and also the way the choices are numbered - I want to put capital letters A, B, C, ... inside \fbox, but I don't know how this can be done.

Answer 1

Try

\usepackage[pointsonleft,showgrayletters,
nototals,forpaper,nosolutions,useforms,usexkv]{eqexam}

and put

\def\exlabelformat{\fbox{\textbf{\theeqquestionnoi.}}\ }

in your preamble.
