So you may take this course ultimately via pass-fail or letter grade and I am more than happy to chat with you about the implications and to sign any paper work such as the stack here that you might need.

你可能希望这门课采用及格-不及格分制或者分数制,我很乐意跟你聊下,两个打分制各自的含义,也可以帮你在这里签到。

I only give, I don't know, about 10% or 20% for getting the right number in a computation. I tell my graders, if the student demonstrates minimal acceptable proficiency that student has to get a passing score.

我只是给，我不知道，10%或者20%的随机概率得到合适的数字,我告诉我的学生们，如果有人想证明,最小可接受的熟练,就是学生们得到一个及格的分数。

A word about grades-- you may in fact take this course pass-fail.

关于分数我有两句话要说，这门课只分及格和不及格两种。
