Mathcrowd Lab

Quick Start

BHCexam.cls provides a LaTeX document class for typesetting exam papers. Mathcrowd Question Bank is using this document to export exam papers as PDF files.

This document class can achieve the following:

  • Supports setting whether to display answers.
  • Supports setting whether to use column layout.
  • Supports setting alignment options.
  • Supports automatically aligning the length of options to the grid.
  • Supports reserving space for fill-in-the-blank answers based on answer length.
  • Supports setting whether to display point values for question groups.
  • Supports reserving space for answering questions.
  • Supports resetting numbering for question groups.
  • Supports sub-questions and sub-sub-questions in short-answer questions.

⚠️ Attention

Given the many exam paper generation platforms available, using this macro package to locally compile .tex files to create exam papers would be highly inefficient for primary and secondary school teachers.

ℹ️ Information

If you are editing math notes or lecture slides and chose LaTeX primarily for its support for mathematical equations, cross-references, and theorem blocks, you might want to check out MMarked.

🎉 Portal

If you already have a private deployment of a question database and are struggling to organize LaTeX question data and generate PDF exam papers, this macro package is what you need. Please go to Integration with the Question Bank.

Usage (Cloud)

You can find an example in this Overleaf project and edit it based on that.

Usage (Local)

  1. Install

unzip it, and copy BHCexam.cls to folder texmf or the same folder as your .tex file to be compiled.

  1. Create example.tex.
\documentclass[answers]{BHCexam}
\begin{document}
\title{XXX中学高一第一学期期中考试}
\subtitle{数学}
\notice{满分150分, 120分钟完成.}
\author{命题人: XXX}
\date{2019.11.15}
\maketitle
\begin{groups}
\group{选择}{本题组共8小题, 共40.0分}
\begin{questions}[ps]
  \question [5] 设$P,Q$为两个非空实数集,定义集合$P+Q=\{a+b|a\in{P},b\in{Q}\}$.若$P=\{0,2,5\}$,$Q=\{1,2,6\}$,则$P+Q$中元素的个数是\key{B}.
  \fourchoices{$9$}{$8$}{$7$}{$6$}
  \begin{solution}{4cm}
    $\because P=\{0,2,5\}$,$Q=\{1,2,6\}$,
    $\therefore P+Q=\{1,2,3,4,6,7,8,11\}$.
    故选B
  \end{solution}
  ...
\end{questions}
...
\end{groups}
\end{document}

delete answers Document Class Options and recompile to generate the student version without answers.

  1. Use xelatexto compile.

Get the exam document using BHCexam.

In the Mathcrowd Question Bank, all exam resources are available for export in .tex document format, and all use the BHCexam package. You can download them locally for editing and compilation. Additionally, you can support the community to gain more free download quotas.
