I have published a survey about this web site that I would like to encourage all students to take. See the explanation. If you complete the survey, you may leave a comment below, on our feedback site (preferred), or send me an email. The survey is anonymous, so all I need is for you to do is let me know you filled it out. For those of you who take it, I’ll give you one extra credit point on your final exam.
I trust you, but I might ask you about the survey to confirm if I have any doubts.
