I want to produce a bubble answer sheet where the number of questions are shown by \qCount. It is always below than 100. Is it possible to produce it dynamically? I cannot print the question numbers before each row and cannot show bubbles within the cells.

desired output: Sample

MWE:

\documentclass[a4paper]{article}

\usepackage{tikz}

\newcommand{\repeatntimes}[2]{
   \newcount\i
   \i=0
   \newtoks\ans
   \loop
      \ans=\expandafter{\the\ans #2}
      \advance\i by 1
      \ifnum\i<#1\repeat
   \the\ans
}

\newcommand{\countRepeatntimes}[2]{
   \newcount\i
   \i=0
   \newtoks\ans
   \loop
      \advance\i by 1
      \ans=\expandafter{\the\ans #2}
      \ifnum\i<#1\repeat
   \the\ans
}

\newcommand{\generateTable}[1]{%
\countRepeatntimes{#1}{\indent
\repeatntimes{4}{\textcolor{lightgray}{\rule{0.9\baselineskip}{0.9\baselineskip}} }\par
}
}

\begin{document}
\def\qCount{80}
\generateTable{\qCount}
\end{document}

I printed out a stepped counter in the loop for the problem number (and another counter for the bubble label) and changed the square \rule to a rotated "0", scaled and stretched appropriately. You can change the size via the numerical arguments to \scalebox{1.4}[1.5]{}. I also made it two column.

EDITED to provide sample filled block.
