I'm going Batshyte crazy here. Out professor is doing what my 2nd-course professor did. If we turn the assessment in early, she'll look it over and tell you if you should work on it, and resubmit. She doesn't tell what to work on, just "look it over and double check your answers," which is perfectly reasonable.
She's sent it back to me a second time now. With a hint at "Look at the example questions, before crafting your own examples." Ok, mini-vent over. Time to get my headache on.
