Great Course but a long course.

我是课程会员，在我们完成了课程后，会发现自己无法获得证明自己成绩的课程证书，因为没有人给你的互评作业评分，我想这是学习课程的人比较少导致的，这是一个恶性循环，因为他存在的问题，会让更多人不愿意去学习并参与它的考试，因为我们的努力无法得到证明。I'm a member of the course. After we finish the course, we will find that we can't get the course certificate to prove our grades, because no one gives you a grade for your mutual evaluation homework. I think this is caused by fewer people studying the course. This is a vicious circle. Because of his problems, more people will be unwilling to study and participate in its exams, because our efforts can't be proved.同学互评等待时间有点久
