This course is pretty much like Lushman’s cs 146 style: lots of things, hard, time-consuming, but learn a lot definitely. If you enjoy cs146, definitely consider taking cs246e.
The course is well-structed. It proposes several problems, and solves them to introduce new concepts.
About 50% more contents than cs 246… and the final project is VIM (if they didn’t change it).
Start the assignments early and go to office hours.
