Study the field before you walk onto it. Most “bad luck” is just not knowing the terrain.

A lot of what gets called misfortune is really missing information. You did not know the deadline moved, or that the teacher marks harder on the second question. None of that was hidden, it was just never looked up. Knowing the ground does not remove chance, but it removes the avoidable part.

Before the next thing that matters, spend half an hour finding out how it actually works. Ask someone who did it last year what surprised them. Read the rules, the rubric, the map, whatever the equivalent is, and you will be surprised how much luck turns out to be homework.
