Graduate-level MBA courses have homework with intense reading requirements. You typically prepare for class by reading case studies and preparing answers that pertain to those case studies. The classes at MBA programs last longer, and are more challenging to remain engaged with, as each class is held by the same instructor for periods of 8 weeks at the time.
