I think problem number one is that you had 200 exams to grade.

This is not an uncomon situation in e.g., math departments across the US. Luckily I've not had to grade more then 60-70 in a single term, or ~200 but a select number of problems in a large course.

Also, second stapled exams with prescribed spaces for answers. So much time wasted just looking for where the answer is.

The children yearn to learn. And the admin cuts costs.
