Slow loading of next (ungraded) exam
Problem: Because of the pandemic, a lot of exams are taken at home and uploaded as a single pdf. This causes the loading of the next (ungraded) exam to be slow (up to 4-5s) when grading, since the entire multi-megabyte pdf has to be loaded.
Proposed solution: Pre-load the next (ungraded) pdf in the background while the the current exam is being graded. This would make the grading process significantly smoother.
