+###img文件夹
+存放了online quizzes的前端界面图片，以及部分使用说明图片
+##PHP文件说明
+1. answerResult.php文件：此.php文件主要处理的业务是，当老师发布测试后，
+   可以通过此界面来查看不同测试的每个学生的答题情况和测试结果，使用步骤如下：
+   1. 打开老师课程管理主界面，然后点击**show Quiz**的按钮
+   1. 根据图片所示进行操作
+    ![使用步骤](/onlineTest/img/instructions/answer1.png "step1")
+      
+2. designTopic.php文件：此.php文件主要处理的业务是，老师可以根据自己的需要，
+   选择添加填空题，选择题和多选题。使用过程比较简单，不做赘述。
+   
+3. downLoad.php文件：此文件用来辅助下载学生测试成绩的.txt文件，由于项目根路径下
+   的文件下载的[DownLoad.php文件](/Download.php)下载文件总是找不到文件，又怕
+   改了源文件后，引入更大的缺陷，故重新编写了一份新的.php文件
+   
+4. LocalRefresh.php文件：用于响应[releaseTest.php文件]中删除题目的请求，以及
+   [answerResult.php文件]中的根据选中的测试名称动态的刷新测试班级编号，和所在此
+   测试班级中的所有学生的学号
+   
+5. releaseTest.php文件：老师编辑测试题目的平台，使用步骤如下：
+    1. 打开老师课程管理主界面，然后点击**Create Quiz**的按钮
+    2. 根据图片所示进行操作
+       ![使用步骤](/onlineTest/img/instructions/release1.png "step2")
+6. student.php文件：学生提交老师布置的测试题目的界面，详细界面请点击[查看](/homepage/screenshots/Student_answer_topics.png)
+7. submited.php文件：当学生答题完成，点击提交按钮之后，系统会自动跳转至此.php文件完成
+   数据的存储
+   
+8. successful.php文件：当老师点击**发布测试**按钮,系统会跳转至此.php文件
+    将数据存入数据中
+   
+9. util.php文件：里面包含一个类，主要是用来存储测试题目的信息
