I'm sure it's vastly different field to field - so I'm kind of hesitant to make too many blanket statements. I'd assume the "unknown unknowns" element is where your advisor would come in and tell you what you need to work on.

Grad courses are all over the place. Some are just a series of chill lectures and discussions. Some are incredibly difficult all consuming and with lots of grueling excruciating problem sets after class... And nothing in between :)

Yes, that would have been nice :(
