What's the current status on accurately grading mistakes? From the exams I remember (Fall 2015), the exams autograded perfect answers well, but gave similar marks to nearly correct, but still wrong answers as complete gibberish. I felt that unless I had the answers exactly correct, it was hard to demonstrate my knowledge of the topic.
In retrospect, I think it was crucially important for students to learn the price of their mistakes. Most of my previous classmates are reputable engineers now.
I was TA for 1911 (I think?) around 2008-2009 and don't recall any automated grading system. It would have been so nice too, as labs would end up with students trying (struggling!) to complete the lab, get the lab graded, and ask questions about lecture material they hadn't yet understood.
The grading would inevitably take up almost all the lab...
We didn't have automated grading for the labs then either, but we did for all the assignments. Still manual marking on style though, which to this day I have complex feelings about.
