You really don't have to bring anything. They'll give you a booklet that pretty much says a lot of the information that they will be talking about. So, I didn't have to take any notes since all of the info I needed to remember was already written in the book.
The second half of the class you will be judging meat. They will provide pencils to mark down your scores. They will also provide bottled water to drink while doing all of this and plenty of paper towels to wipe your hands with. They also provided us with a clamshell container to carry any leftover food home.
So, you really don't have to bring anything with you. It's a fun four hours and the best class I had ever taken.
