添加问题类别并使其出现在考试类别的成绩表中

Question

我们希望根据学习成果对考试中的问题进行分类。每个问题将有一个或多个类别编号。这些数字应该出现在成绩表中。例如，我可以通过像这样修改奖励点环境来创建自定义组合成绩表组（参考：类似问题但不相同)：

\begingroup
  \chbpword{Category}
  \settabletotalbonuspoints{}
  \renewcommand{\bonuspointsofquestion}[1]{}
  \combinedgradetable[h]
\endgroup

并得到这个：

但是我不知道如何为问题分配类别并将其显示在成绩表中。或者如果有任何其他方法可以实现这一点，我将不胜感激。

我希望它显示如下：

提前致谢。

我在这里定义了一些命令，这些命令允许根据exam课程本身的代码为考试课程文档中的问题分配类别。我认为将大部分代码放在一个文件中会更清楚category.sty，该文件位于答案的末尾。我进行了一些测试，我认为它在大多数情况下应该可以工作。但我注意到它可能无法与该包一起使用hyperref。

定义的新命令如下。

• \newcategory{<name>}{<label>}。此命令允许在考试中定义新类别。<name>是类别的名称，它将以文本显示，<label>是代码中访问类别的标签。此命令应放在序言中。
• \category{<label>}. 返回与标签关联的类别的名称<label>，全部为小写字符。
• \Category{<label>}。与 相同\category，但将类别名称的首字母大写。
• \categorynumber{<label>}。返回与标签关联的类别的编号<label>。类别按\newcategory命令中定义的顺序进行编号。
• \categorize{<label>}。用于项目中\question。将相应问题与标记为的类别关联<label>。该\categorize命令只能将单个标签作为参数，但\categorize可以对同一问题使用多个命令，以将问题与多个类别关联。
• \categorytable。创建一个显示类别名称和相应编号的表格。无需调用类别表即可对类别进行编号。

如果已定义类别并对问题进行分类，则类别将显示在水平完整评分表（成绩、分数、奖励或组合）中（如果它们是按问题索引的）。在部分或垂直评分表中，或在按页面索引的表中，类别将被忽略。

这里有一个小例子来展示大多数命令的用法。

\documentclass[addpoints]{exam}
\usepackage{wrapfig}
\usepackage{category}

\newcategory{Analysis}{cat:an}
\newcategory{Topology}{cat:topo}
\newcategory{Algebra}{cat:alg}

\begin{document}

\begin{wraptable}{r}{0.2\textwidth}
\centering
\categorytable
\caption{Example of \textbackslash\texttt{categorytable}.}
\end{wraptable}

The categories used in this exam are \category{cat:an} (\categorynumber{cat:an}), \category{cat:topo} (\categorynumber{cat:topo}) and \category{cat:alg} (\categorynumber{cat:alg}).

\medskip\combinedgradetable[h]

\begin{questions}
  \question[15] \categorize{cat:an} First question.
  \question[25] \categorize{cat:an}\categorize{cat:topo} Second question.
  \question[30] \categorize{cat:topo} Third question.
  \question[30] \categorize{cat:alg} Fourth question.
  \bonusquestion[5] \categorize{cat:topo}\categorize{cat:alg} Bonus question.
  \bonusquestion[5] Bonus question, not categorized.
\end{questions}

\end{document}

默认情况下，单词“Category:”将显示在成绩表中相应行的开头，但可以使用命令\hcword{newname}、\bhcword{newname}和\chcword{newname}将关联表（分别为成绩、奖金和组合）中的“Category:”替换为“newname”。similar 命令\cwordctbl允许更改 中显示的名称\categorytable，默认情况下为“Categories”。如果问题未分类，则此问题的类别行中显示的内容由命令定义\nocword。默认值为\nocword{--}，但类似调用将替换--为参数。

以下是category.sty文件。如果您希望将该代码放在序言中，只需加载包refcount，并将以下代码的前三行以外的所有内容放在\makeatletter和之间\makeatother。
