How to repeat the page-contents on the same page

Question

Multiple copies of short page on one sheet of paper

I am a school teacher. I have the following need. I have to distribute a large number of quizzes to about 200 students each week. Each quiz text is very short; just a small header which is followed by 3/4 lines of text.

So I want to repeat the entire quiz contents verbatim (including the header/footer, if any), on the same A4 size page. This way I can print 4 to 5 pamphlets on a A4 size paper and then cut them to distribute (to save paper and thus trees).

I saw the leaflet class and its documentation, but am not sure whether this can be achieved with leaflet class. Also the labels package doesn't seem right for this.

Given below is the TeX code for a sample quiz that I am trying out.

\documentclass[9pt,a4paper]{exam}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[compact]{titlesec}
\pagestyle{headandfoot}
\firstpageheadrule
\runningheadrule%remove comment for horizontal line at top of every page.
\providecommand{\abs}[1]{\lvert#1\rvert}

\titlespacing{\section}{0pt}{2ex}{1ex}
\titlespacing{\subsection}{0pt}{1ex}{0ex}
\titlespacing{\subsubsection}{0pt}{0.5ex}{0ex}
\newcommand{\attempt}[1]{Attempt any \textbf{#1} of the following.}
\pointsinrightmargin \extraheadheight[.7in]{0pt}
\firstpageheader{\textbf{Time: 20 min}}%left
                {\textbf{\large Name of the institute}\\
                \textbf{Subtitle if any\\
                 Quiz/Test - 1  
                  }
                }%centre
                {\textbf{Date:\hspace{10 mm} Marks:}}%right
\runningheader{\ifcontinuation{\textbf{Q. \ContinuedQuestion. Continued\ldots}\hrule}
                                { }}%left
              { }%centre
              { }%right
\renewcommand\questionlabel{\hspace{-10pt}\textbf{Q.\thequestion.}}
%remove above Comm to print Ques lable
\footer{ }%\oddeven{}{\iflastpage{}{\textbf{[P.T.O.]}}}}%left
             {\iflastpage{}{}}%centre
         {\iflastpage{}{\textbf{[P.T.O.]}}}%right
\pointformat{\textbf{[\themarginpoints]}}%print points in brackets.
