How to reset exercise counter in XSIM

Question

How can I reset the exercise counter within the same exercise type. I don’t want to create different exercise types as I want to create question bank and use collection option. I have attached MWE and required output. I am beginner and I am open even if some one can improve my code by using XSIM.

My MWE

\documentclass[a4paper,12pt]{article}
\usepackage{xsim}
\usepackage{tasks}
\settasks{
label = (\theexercise\arabic*) ,
label-width = 5ex,
item-indent=6ex
}
\DeclareExerciseType{question}{
  exercise-env = question ,
  solution-env = answer ,
  exercise-name = Question ,
  solution-name = Answer ,
  exercise-template = item ,
  solution-template = solution ,
%   exercise/the-counter = \arabic{exercise}. ,
  counter = exercise, % shares a counter with the `exercise' type
}
\DeclareExerciseEnvironmentTemplate{item}
  {\item[\GetExerciseProperty{counter}]
  \GetExercisePropertyT{points}
    {%
    \marginpar
      {%
      \par\vspace{2.5ex plus .2ex}
      [\printgoal{\PropertyValue}]%
      }%
    }%
  }%
  {}
\DeclareExerciseEnvironmentTemplate{solution}
  {\item[\GetExerciseProperty{counter}]}
  {}

Answer 1

The user cabohah has given the right direction to the solution in the comments.

After adding the setting within=section to \DeclareExerciseType, all you have to do is to redefine the \section command so that it doesn't display the number section at front of it. This can be do with the titlesec package, as showed.

In this solution, you are using the \section command, not the starred version \section*.

So, with this code:

\documentclass[a4paper,12pt]{article}
\usepackage{xsim}
\usepackage{tasks}
\settasks{
label = (\theexercise\arabic*) ,
label-width = 5ex,
item-indent=6ex
}
\DeclareExerciseType{question}{
  exercise-env = question ,
  solution-env = answer ,
  exercise-name = Question ,
  solution-name = Answer ,
  exercise-template = item ,
  solution-template = solution ,
%   exercise/the-counter = \arabic{exercise}. ,
  counter = exercise, % shares a counter with the `exercise' type
  within=section %% ADDED via comment by "cabohah"
}
\DeclareExerciseEnvironmentTemplate{item}
  {\item[\GetExerciseProperty{counter}]
  \GetExercisePropertyT{points}
    {%
    \marginpar
      {%
      \par\vspace{2.5ex plus .2ex}
      [\printgoal{\PropertyValue}]%
      }%
    }%
  }%
  {}
\DeclareExerciseEnvironmentTemplate{solution}
  {\item[\GetExerciseProperty{counter}]}
  {}

\usepackage{lipsum}
\xsimsetup{
    exercise/the-counter = \arabic{exercise}.,
    %exercise/within = section,
    % answer/print = true,
}
% Modifying the \section command
\usepackage{titlesec}
\titleformat{\section}[hang]%
{}%
{}%
{0pt}%
{\Large\textbf}%
\begin{document}
\section{Section A}
\begin{questions}
\begin{question}[points=4]
    \lipsum[66]
  \end{question}
  \begin{answer}
    \lipsum[66]
  \end{answer}
\begin{question}
    Answer the following questions.
    \begin{tasks}
      \task \lipsum[75]
      \task question.

\section{Section B}
\begin{questions}

\begin{question}
    Answer the following questions.

      \task \lipsum[75]

    \lipsum[66]
  \end{question}
  \begin{answer}

\end{questions}
\end{document}

you obtain that:
