Sorry, I answered this by email when it was asked, but I see that it wan't posted.
The questions you got wrong are always available after you take the quiz or test. Beyond that you could ask about specific questions here on the board or come to my office hours.
I do have reasons for my policies though they may not impress you as good ones. In this case the point is to encourage students to learn the material rather than reach the correct answer by the process of elimination. I do not regard a phrase like "in lecture" as vague. You always know what lecture is being referred to and with questions like that the answer is always explicit.
I understand that and I respect your policies.
This is what we're referring to when we mention the "according to lecture" as being vague. When we get our quiz results, sometimes the question isn't really made clear and I forget which one it was. Sometimes there are multiple questions that show up like this in one quiz. Makes it a little confusing.
