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!

Quanta article about a fast linear algebra algorithm devised by GaTech faculty

New York Times article about the Napolean Dynamite problem

Recommendation algorithm with SVD

Here is a list of suggestions for doing well in a math class. And here is an addendum.
