Linear Algebra playlist exercises

Khan Academy has a great list of videos covering Linear Algebra. However, that whole section is missing any exercises, except for a few very basic ones regarding vectors.

There has been a previous inquiry about this about a year ago: https://khanacademy.zendesk.com/hc/en-us/community/posts/201857070-Linear-Algebra-Exercises?input_string=Linear%20Algebra%20play

What I'm wondering is whether any progress is being made on the content of the linear algebra section? I see that KA has added a lot of new exercises for many other areas recently, but in my opinion linear algebra has been somewhat neglected. I think its a shame to have such an extensive list of videos, but with no accompanying exercises which allow students to check their understanding.
