Here you can find the linear algebra section: https://www.khanacademy.org/math/linear-algebra

As you go through the material there are quizzes and exercises. 

Hi Eleni. The original poster has a valid point. The course has quizzes in the very first section then they stop. The teaching goes on just no way to assess if you really understand the material. Unfortunately the material does not line up with Schaum’s Linear Algebra workbook so exercises are needed. I guess this problem has been around for 7 years so I’m going to see about Strang or Anton.
