I/O Intro Grad courses

Hello all,
If anyone’s taken Survey of Industrial Psych or Survey of Organizational Psyc, can you tell me what you thought of the classes? A lot of outside reading, work, assignments, studying? I took Psych 611 which did require a lot of hours of outside work for me (returning to school as a mom after a very long gap). I’m sure these classes are easier, but how much easier?
