                【使用方式】<br>
                1.点开你想要的课，确保这课的时间段没有冲突。<br>
                2.滚动到网页最下方，点击“录制点击数据”，然后点右边的“选课”<br>
                3.中间会弹出提示“已无余量，不可选”的提示，点确定。<br>
                4.接着点击网页最下方的“开始模拟点击”，观察按钮上方提示，“正在等待余量放出，请耐心等待……”则为正常<br>
                5.不要关闭网页，不要关闭电脑，最好把网页最大化，等待抢课成功。<br><br><br>
