What annoys you?

In my first year, the guys from our group had their practical assignments replaced with helping move desks from one classroom to another, and in subsequent years, I just skipped the practical assignments, so draw your own conclusions.

I only had it before my first year. I cleaned the floor in one underground passage between buildings (quite a job, the dirt somehow seeped through the walls, and over the year, it was literally a swamp). But in the end, I was happy with the result. I don't remember it ever being that clean before or after, haha.
