Hi, folks! I'm teaching a course on category theory at UCR, and there are some hand-written notes here:
* [Category theory course](https://johncarlosbaez.wordpress.com/2018/10/13/category-theory-course/).
I'm not sure it's possible to follow the course from these notes; there's a lot that I say out loud, and even some that I write on the board, that didn't find its way in here. But they might at least give you some ideas for things to study.
