She used online videos from Fall 2020. Class times were TA/office hour sessions. Lecture notes are long, but once you understand them it's good. You can practice by solving the examples she gives in lectures - you don't need extra questions from a textbook. The labs are the hardest part. 2hr 30min session are allocated, but I usually needed 5hr to finish it. You REALLY need to think things through for the labs. The final project is a beast. Spent about 40-50 hours in two weeks trying to finish it. If you don't understand the labs, you won't understand the final project.

Course content is super helpful for everything in the future of engineering.

Awesome. She's hardcore, but it's because she cares and wants you to learn as much as possible in 3 months.

Don't focus on textbook stuff. Do lectures. Solve the lecture problems via self-study. Focus on doing well in labs.
