- If you're looking for the most complete introduction to Linear Algebra (which will also take longest), go through the MIT course.
- If you want to build up an understanding of Linear Algebra more quickly (at a similar level of rigorousness, but at the expense of completeness), take the Princeton course.
- If you are looking for a course that dives straight into the computational side of Linear Algebra, give Rachel Thomas' course a try.
- If you already know some basic linear algebra, Gil Strang's Matrix Methods course might be worth watching.
- For a review of Linear Algebra, Khan Academy's and Trefor Bazett's videos are the way to go.
