更改考试类别中的缩进

Question

我目前正在参加考试，需要左侧的特定缩进以匹配以下内容：

我一直在使用考试类，现在已经整理好了右边距和考试分数，但我的左缩进不正确。正如您在下面看到的，问题后面的信息已经缩进，枚举也是如此。有什么想法可以解决这个问题吗？我有点新手！

Answer 1

看来您希望部分和子部分缩进相等。我随意选择了\leftmargini。

\documentclass{exam}
\usepackage{showframe}% MWE only, to show first margin
\marksnotpoints

\renewcommand{\questionlabel}{Question \thequestion.}
\renewcommand{\questionshook}{\leftmargin=0pt%
  \labelwidth=-\labelsep}
  
\renewcommand\partlabel{\hbox to \labelwidth{\alph{partno}.\hfil}}
\renewcommand{\partshook}{\setlength{\leftmargin}{\leftmargini}%
  \setlength{\labelwidth}{\dimexpr \leftmargin-\labelsep}}
  
\renewcommand\subpartlabel{\hbox to \labelwidth{\thesubpart.\hfil}}
\renewcommand{\subpartshook}{\setlength{\leftmargin}{\leftmargini}%
  \setlength{\labelwidth}{\dimexpr \leftmargin-\labelsep}}
