Pre-grade Homeworks

Since lots of folks are probably submitting their answers ahead of the deadline, do you have a test harness that could run your grading algorithms against the submitted homeworks?

It seems like it would be a good way to see if there was either widespread confusion about what the question was asking and a good way to unit test the grading

I've been assuming that the quick turnover after the due date (HW3 turned around at 5:00PM PST exact) means that the answers are being evaluated on submit, and simply revealed once the deadline passes. (Also makes more sense from a load-balancing perspective).

The argument, then, would be that the Udacity team should run analytics as the HWs are coming in (maybe with some attention to priors, like P(HW3.4 incorrect|HW3.6 correct) = {low})

Deleted my earlier comments since I see you made the same point first (but the busy server prevented me from seeing it). I, too, would assume Udacity are already grading upon submission, and would also encourage them to monitor statistics like this throughout the week to help catch similar issues before they become major ones.

Really good suggestion. Since I got here by a comment on AndyUdacity's post on the 3.4 homework, I think its safe to assume he's probably read it by now.
