考试时打乱题目顺序

如果我想打乱题目顺序，准备四份题目相同，但题目编号不同的试卷，该怎么办？

在此处输入图片描述

 \documentclass[12pt,a4paper]{exam}
    \usepackage{amsmath,amsthm,amsfonts,amssymb,dsfont}
    \setlength\parindent{0pt}
        %usage \choice{ }{ }{ }{ }
        %(A)(B)(C)(D)
        \newcommand{\fourch}[4]{
        \par
                \begin{tabular}{*{4}{@{}p{0.23\textwidth}}}
                (a)~#1 & (b)~#2 & (c)~#3 & (d)~#4
                \end{tabular}
        }

        %(A)(B)
        %(C)(D)
        \newcommand{\twoch}[4]{

    \begin{document}
     \begin{questions}
    \question If $a = 3 + i$ and $z = 2 - 3i$ then the points on the Argand diagram
    representing az, 3az and - az are
    \choice{Vertices of a right angled triangle}{ Vertices of an equilateral 
    triangle}{Vertices of an isosceles triangle}{Collinear}
    \question If z represents a complex number then $\arg (z) + \arg\left(\bar z\right)$ is 
    \choice{$\dfrac{\pi}{4}$}{$\dfrac{\pi}{2}$}{0}{$\dfrac{\pi}{6}$}
    \question If the amplitude of a complex number is $\dfrac{\pi}{2}$ then the number is
    \choice{ purely imaginary}{purely real}{0}{neither real nor imaginary}
    \question The value of $i + i^{22} + i^{23} + i^{24} + i^{25}$ is
    \choice{i}{-i}{1}{-1}
    \question The volume generated by 
    rotating the triangle with vertices at
    (0, 0), (3, 0) and (3, 3) about x-axis is
    \choice{$18\pi$}{$2\pi$}{$36\pi$}{$9\pi$}\end{questions}
    \end{document}

    \end{document}

也就是说，我需要将上面给出的试卷标记为代码 A。并且我需要打印另一张标记为代码 B 的试卷，并且在此试卷中，第一个问题的代码 A 应该在问题编号 5 中（比如说），类似地，其他问题也应该有不同的位置......
