java考试在线阅卷 编程题阅卷思路_course

要做一个在线考试系统，其中有java编程题，想要实现自动阅卷，不知道怎么实现。有知道的可以说下思路或者采用什么技术么? 系统用的jsp和springmvc框架（至少可以抓取运行效果和异常，以及语法错误等）

VBA实现office操作题自动判分_course

计算机考试系统中利用VBA实现对office操作题的自动判分，希望有源码！谢谢啦！

在线考试系统，随机生成了题目，怎么阅卷，用的struct2_course

struct2，迭代question类，题目下，有单选提或者多选提，题目是数据库随机生成的，怎么写，可以题目号和s：checkboxlist选的值对应返回，然后批卷？

使用C语言编写单项选择题标准化考试系统，谁会啊？？_course

使用C语言编写单项选择题标准化考试系统。 一、功能要求： 1、每个试题包括题干、4个备选答案、标准答案。（使用二维数组实现） 2、试题录入：可随时增加试题到试题库中。（使用二维数组实现） 3、答题：用户可实现输入自己的答案。（用户从键盘输入） 4、自动判卷：系统可根据用户答案与标准答案的对比实现判卷并给出成绩。（与数组中存放的正确答案对比）

XML格式的定义是什么意思？做了一个在线考试系统，要求解释XML文件的格式定义，求解_course

应该先给出xml的格式定义，再讲述生成xml文件的关键代码，例如先创建个builder，再如何创建节点，如何新增节点属性，如何添加节点内容，如何创建子节点或者 是你可以举一个只包含一道选择题，一道填空题和一道编程题的试卷的例子解释xml文件的格式定义。就像oj那样，举个输入数据的例子，文字解释输入数据的格式！ 具体XML的代码如下 using DIT.NET.Model; using System;
