Question

I need to have four different question papers in which the order of the above questions only changed and i need to give the answer for the respective question paper in a separate sheet. so kindly help me to prepare those question papers from this. That i need to prepare another question paper by shuffling the questions and i need to give the answer respectively. How should i do?

one more question ##

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...??

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 and similarly others also should have different positions...

thank you for your help in advance...

Answer 1

I incorporated this answer to solve your problem. After you write your four choices, put the correct choice (a, b, c, etc.) in braces as a fifth choice.

Answer 2

You can use the automultiplechoice package. With the help of the associated (open source) software, you will be able to correct the answer sheets automatically from the completed answer sheets scans. As an example:

\documentclass[a4paper]{article}
\usepackage[box,completemulti,separateanswersheet]{automultiplechoice}
\usepackage{multicol}
\begin{document}

\AMCrandomseed{1237893}

\element{general}{
  \begin{question}{coll}    
    If $a=3+i$ and $z=2-3i$ then the points on the Argand diagram representing $az$, $3az$ and $-az$ are
    Among the following persons, which one has ever been a President of the French Republic?
    \begin{multicols}{2}
      \begin{choices}
        \wrongchoice{Vertices of a right angled triangle}
        \wrongchoice{Vertices of an equilateral triangle}
        \wrongchoice{Vertices of an isocele triangle}
        \correctchoice{Collinear}
      \end{choices}
    \end{multicols}
  \end{question}
}

\element{general}{
  \begin{question}{arg-sum}    
    If $z$ reprensents a complex number then $arg(z)+arg(\bar z)$
    \begin{multicols}{4}
      \begin{choices}
        \wrongchoice{$\pi/4$}
        \wrongchoice{$\pi/2$}
        \correctchoice{$0$}
        \wrongchoice{$\pi/6$}
      \end{choices}
    \end{multicols}
  \end{question}
}

Answer 3

You can also have a look at the esami package, which provides simple commands to automatically achieve what you want.

The doc files for the package contain various examples, but if you need any help to set up your exam sheet, please feel free to ask.
