Here is a reference sheet containing most theorems and definitions that you will learn (and be responsible for knowing) over the course of the semester.

Here is the interactive row reducer.

You can find old quizzes and exams here and here, for example

There are some games related to the course here.

You can play Lights Out here. If you want to know what this has to do with linear algebra, ask your instructor!
