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