工具介绍
选择题批改最耗时间的不是判对错，而是把四十份答卷一条条对着答案数；数到一半还得回头核一遍。 Grading multiple choice is less about judging than about counting forty sheets against a key one by one, and then double-checking halfway through.
答案和答卷各贴一次，错题号直接列出来，谁错了哪几题一眼看到，讲评时按错得最多的题先讲。 Paste the key and the sheets once, get the wrong item numbers listed, see at a glance who missed what and start the review with the worst items.

常见问题
姓名能自动识别吗？Are names detected?
行首是中文（或非字母数字）会被当成姓名，后面才是答案；不写姓名也可以，会自动编号。A leading Chinese (non-alphanumeric) token is taken as the name and the rest as answers; without a name the student is numbered.
多选题能批吗？Can it grade multiple-choice questions?
不能，这里只做 A 到 H 的单选逐题比对；多选要另想办法，本工具会把多写的字母按错处理。No, it compares single choices A to H only; extra letters are counted as wrong, so multiple-answer items need another route.
答案少写一题怎么办？What if an answer is missing?
按空白计，不算对也不占分，同时会在结果里单独标出空题号。It counts as blank: no points, and the item number is listed separately as blank.
能导出成绩表吗？Can I export a score sheet?
不能，本工具只做即时核对；需要表格请把结果手抄或截图。No, it only checks in place; copy or screenshot the result if you need a spreadsheet.
