# Shuffling questions in exam

If I want to shuffle the question to prepare four different questions papers having same questions but with the different question numbers, what should I do?

 \documentclass[12pt,a4paper]{exam}
\usepackage{amsmath,amsthm,amsfonts,amssymb,dsfont}
\setlength\parindent{0pt}
%usage \choice{ }{ }{ }{ }

\end{tabular}

\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}

That is I need to mark the question paper given above as Code A. And I need to print another question paper which marked as Code B and in this question paper the first question Code A should be in question number 5 (say) and similarly others also should have different positions...

• May be you should try something else like exsheets.

• az, 3az and - az should be $az$, $3az$ and $- az$. There are other places with the same formatting problem. Dec 20 '14 at 23:56
• You can also have a look at the esami package which does what you want. Dec 21 '14 at 0:06
• This python script seems to shuffle the questions: github.com/gcalmettes/examRandomizer But this is an external script and there seems to be so bugs. Mar 10 '20 at 10:40
