For Summer, it was all online and Tung streamed his lectures on YouTube, which I liked. For me personally, the material of this course was pretty interesting, probably because I'm EE. But it was also because his lectures were clear and his teaching style was very engaging for me. We had weekly Quizzes which were generally easy, if you watched the lectures and did practice/HW problems. Most of the HW was easy. The final exam was fair as well. It was like watching a streamer everyday, he has an intro video and everything.
