考试班级成绩表 - 报告平均分数？

我有时会发布我以前的考试，我认为如果首页上的成绩表报告了每个问题的平均分数（从考试那一年开始），这些考试作为参考文件会更有用。我的目标是在标准成绩表中添加一个额外的“平均”列。

我已经创建了一个 MWE，它得到了一些东西关闭通过劫持奖励积分机制（我不使用）来实现我想要的效果。问题是，我希望能够为常规问题“分配奖励积分”（记录平均分数），而不是像我在 MWE 中所做的那样为此添加单独的部分

\documentclass[addpoints]{exam}

\begin{document}

% Rename "Bonus Points" entry in grade tables

    \bvpword{Average}  % Vertical Bonus Tables
    \bhpword{Average}  % Horizontal Bonus Tables
    \cvbpword{Average} % Combined Vertical Tables
    \chbpword{Average} % Combined Horizontal Tables

% Combined point table  
    
    \combinedpointtable
    
% Questions

    \begin{questions}
        \question
        \begin{parts}
            \part[20] Why?
            \bonuspart[15] Dummy part to indicate that the average score on this question was 15
        \end{parts}
        \question
        \begin{parts}
            \part[20] Why not?
            \bonuspart[15] Dummy part to indicate that the average score on this question was 15
        \end{parts}
    \end{questions}

\end{document}

是否有一种简单的方法可以为常规问题分配加分，或者是否有更好的方法来记录考试类别中的平均分数？

答案1

我想到了一种只在表格打印时修改奖励机制的方法。关键思想是只劫持最低级别的函数（负责从文件中报告奖励积分的函数），并使用开关使其恢复正常。MWE 是

\documentclass[addpoints]{exam}

\begin{document}

\makeatletter

% New variables

  \def\avgword#1{\def\@avgword{#1}} 
  \avgword{Average} % Used in column/row heading

  \newif\if@bonus@is@average
  \@bonus@is@averagefalse
    
% Command for writing average score to file 

    \newcommand{\avgWas}[1]{%
    \if@filesw
      \ifnum \value{question} > 0\relax
        % Now do bonus points:
        \immediate\write\@mainaux
          {\string\gdef\string\avgpointsofq@
            \romannumeral \csname c@question\endcsname
              {#1}}%
      \fi
   \fi
   }
   
% Re-write bonuspointsofquestion to possibly report average points instead (depending on value of \@bonus@is@average)
   
    \let\bonuspointsofquestion\relax
   \newcommand{\bonuspointsofquestion}[1]{%
      \if@bonus@is@average%
        \@ifundefined{avgpointsofq@\romannumeral #1}%
        {\mbox{\normalfont\bfseries ??}}%
        {\csname avgpointsofq@\romannumeral #1\endcsname}%
      \else%
        \@ifundefined{bonuspointsofq@\romannumeral #1}%
       {\mbox{\normalfont\bfseries ??}}%
       {\csname bonuspointsofq@\romannumeral #1\endcsname}%

我没有尝试同时报告常规积分和奖励积分，因为这不是这里的目标用例。这可以做到，但需要重写几层不同的表格写入函数来添加额外的行/列。
