It is hard but so worth it. It is hard to overstate how good it is. The pedagogy, the charisma/style, the fact he cofounded openai and worked for Elon but is a modest as say a math tutor popping into your house to teach you some math!

There is a great discord community attached too which makes a big difference.

What is missing from this and another course I did and is very hard to find is multivariate calculus on linear algebra. I feel motivated to create a resource on it because its pretty hard. For example how to differentiate matrix operations where broadcasting has been involved. Not just the how but really grokking it into working memory.
