考试文档类别：是否可以“不打印”解决方案并删除框？

在 mwe 中，我已经注释掉了打印解决方案命令：%\printanswers。

正如预期的那样，这会产生带有空框的问题。“答案”实际上是分步解决方案，导致出现如下所示的大框。

在此处输入图片描述

是否可以注释掉打印答案命令并删除方框？（原因：回收空方框创建的所有空白区域。学生在单独的纸上展示作业。）

或者，我应该创建 2 个版本：（1）仅问题（即没有解决方案框的代码）（2）问题+像这样的分步解决方案：

在此处输入图片描述

练习包含 15 至 30 个问题。因此，任何使流程更高效的建议都十分受欢迎。

非常感谢您花时间阅读并回复我的帖子！

答案1

添加代码来测试解决方案是否正在打印。在第二种情况下，框被移除。

请注意 被[5cm]替换为[\SolutionSpace]并被{\vspace{0.5cm}}注释掉。还可\usepackage{color}按照\usepackage{xcolor}类的要求使用 代替exam。

笔记。如果您的学生总是使用单独的答题纸，您可以删除所有出现的[\SolutionSpace]。如果您想在问题下方保留一个空间来写解决方案，这是一个可选参数。

所以代码可以简化。
