我正在使用文档类extarticle为我的班级制作测验、作业等。在 pdf 输出文件中，有很多空间未使用。这导致额外的纸张消耗。我们如何使 pdf 输出更紧凑以避免纸张浪费。
我将非常感激任何对此提供的帮助。

下面给出了一个最小示例。pdf 输出包含两页，但内容非常简短，应该可以轻松放在一页甚至更少的页面上。减小字体大小是一个有用的技巧，但如果我不想减小字体，还有其他方法可以优化打印区域吗？

答案1
- 不要使用
\begin{center}。\centering而是在组内使用 \bf{text}是错误的。使用\textbf{text}或{\bfseries text}- 同样适用于
\Large{text}，应该是{\Large text}
话虽如此，您可以使用包减少默认边距geometry。

答案2
当然，有一些很棒的测验软件包，但您可以创建自己的风格。在这里，我将纸张设置为列，因为 A4 页面不太适合打印宽行，并且为了有效利用空间，需要更多列。
我还创建了一些宏，以便于使用，并提高一致性。现在，您只需使用，\Question{points}{question}而不必使用大量格式和冗余代码。我还使用了 no parskip-package 来删除缩进，因为您显然不希望在这里这样做。
现在会自动计算可用的最大分数和总数并将其放入头表中。
编号的输出equation已更改，因此它使用罗马数字，正如您所希望的那样。您不需要手动添加它。
