> I remember spending several hours in one instructors office trying to figure out where I was going wrong. She was also confused because all of my intermediate work was correct, but I always came up with the wrong answer In grad school, I was a TA for some undergrad EE courses. We (the TAs) and professor corrected tests together and whenever we encountered a wrong answer, we'd always replicate the student's work to find where things went wrong so we could a) point it out and b) give partial credit whenever possible. For a class of 120 students, it took four of us two days to get through all of the tests.
