I couldn't get a sense of what I would learn just from the titles of each lecture, but when I actually took the course, I found it easy to understand because it was well-structured and taught comprehensively within 6 lessons in the video. The videos weren't too long or too short, and it wasn't just theoretical lectures - having practice problem explanations at the very end was really great. I'd like to read the books you recommended as well. I'll make sure not to forget what you taught and put it to use at my company. Thank you for the excellent lecture.
