Students are beginning to email me while tests are live, asking for clarification of the question or for help in deciding among a couple of options. I do have to pay attention in case it’s a sign there is something wrong with a question. But it never is. Instead, I have to email back saying that out of fairness to the rest of the class, I can’t respond while the test is live. Where relevant, I’ll add that I think the question is fair, or that no one else has emailed with that particular concern. And then usually I find myself finishing: It is good that you are reading the question very closely and thinking hard about it. You need to. But do not over think the answer.
This is one of those posts I’ll link to when I am responding to such requests in future.
