I have a homework. The problems chosen by the lecturer are often not in arithmetic sequence so I have to change the problem counter (and its solution counter) manually.
\documentclass[preview,varwidth,border=12pt]{standalone}
\usepackage{exsheets}
\SetupExSheets
{
solution/print=true, % default false
}
\begin{document}
\begin{question}
How to change the counter of problems or questions and solutions to start from any number?
\end{question}
\begin{solution}
I don't know the counter name!
\end{solution}
\end{document}
