When I took this class, it was just 35 pre-recorded videos online. There were no midterms or homeworks, the class was completely graded on the final. The final wasn't too bad at all if you took good notes and read the course reader. The videos were about 10-30 minutes each and pretty clear, but it really felt more like a Coursera course rather than a UCLA class. The material is interesting, but I wish the course went more in depth. If you need to fulfill an elective, this is a good class to take, but if you're interested in the material I'd try taking it in person.
