Voting rules: Choose the age range you think is the most difficult!
This is a community-based ranking of the most difficult age range. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or age range is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each age range once every 24 hours. The rank of each age range is then calculated from the weighted sum of all up and down votes.
