7C is comparable to the rest of the classes in the 7 series. Although there's much more content to cover, most assignments only require a surface-level understanding. Many of the questions focus on understanding how to read diagrams and graphs. Soroosh will not know the answer if you ask him any hard conceptual questions, but it is his first quarter teaching the class, and he does spend a lot of time going over the diagrams which are actually tested on the final and midterms.
