I would like this, too.

Daniela, if you answer this one, I can't speak for the original poster, but I don't need any smiley faces inserted in your reply. Thanks.

I know that Khan Academy is adding some exercises to Multivariable Calculus this July, but I would LOVE for there to be exercises for Linear Algebra by the Spring semester. I am trying to manage teaching Dual-Enrollment both in a hybrid and entirely virtual environment, and my school district isn't taking any new applications for software approval. Having exercises for my students to practice with support is really important when I don't "see" them for class time, and many of them watch my lectures asynchronously. Having them submit pictures of their work for feedback is manageable every once in a while, but grading 80 pictures of multivariable calculus or linear algebra work every week is A LOT when I'm trying to focus on engaging my students, creating materials, hosting live sessions, and doing the same for an entirely different subject. 

Please add exercises for Linear Algebra!
