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