All official WCA events are on the schedule of the World Championship. The number of rounds varies per event, as well as the number of competitors that will proceed to the next round.
The provisional competition (updated in July 2021) schedule is based on 800 competitors and 45 competition stations in the main hall. The number of registrations could lead to important changes to the schedule such as the duration of rounds and cumulative time limit. Eventually there will be cutoff limits.
