Study up on Calculus if you need

I highly recommend looking at the Khan Academy material on derivatives 1 and matrix multiplication 2 if (like me) you left calculus back in high school. Getting a solid understanding of those concepts was important foundational knowledge for other concepts I encountered in this chapter.

I always recommend actually working on some real datasets, especially Kaggle competitions. link
