I'm writing this review after completing 75% of the course. I'm a liberal arts graduate who gave up on math. I'm taking this course because I want to go to graduate school for data analysis. It might be different for everyone, but it was so difficult for me that I think I replayed each lecture about ten times. Each lecture is relatively short at 30-40 minutes, but there were times when I spent almost an entire day trying to understand just one lecture. Honestly, no matter how well the instructor explains it, the linear algebra content itself is so abstract... In the end, I had to go back and review the lecture materials on my own and replay the instructor's explanations several times. When I first listened, I thought "What on earth is he talking about?" but after replaying it about ten times, I could understand what he was saying. I barely, barely finished up to eigenvalues and vectors. I really thought I was going to throw up. Now that I'm finishing this, I have this baseless confidence that I'll be able to take any math course. However, the lecture slides have a black background... which made it hard to take notes, so that was quite disappointing.
