I don't know if the online classes will cover the same, less, or more material than the equivalent classes at Stanford. However, if they cover the same material, both classes combined are about half of a full-time student's workload in terms of academic units, but SUBSTANTIALLY more than half of a full-time's student's workload in terms of effort/hours. The material is difficult and the assignments are challenging. Expect to spend 10-20 hours of intensive work per week on each class.
