Workload is higher than many other schools, and according to some websites/colleges rated, Midd students spend more time studying than at many schools in their peer group.
Saying that, neither of my children seem to be overwhelmingly burdened. Son 1 has time to work 10 hours a week in a campus job, participate in 2 clubs, and do political activities.
Son 2 has time to participate in a varsity sport in season, club sports, and many cultural activities.
Both went to a public HS in NY and did IB. This is TONS more work than that, but they are learning a lot and have become experienced at time management.
