Pro Rich practice in Khan Academy style
For every lesson, it has a "worksheet" where you can attempt to solve problems in the set. And for each problem, there's a "check" button where you can see if it's right or not, and also there're "hint" and "solutions" for each problem.
The website also uses the "smart textbox" for entering equations conveniently like what Khan academy does.
Pro Very well completed in content
Explicit in content for pretty much everything you need to learn about Linear algebra.
Con Teaching skills need to be improved
Con Too much "Polynomial vectors"
He's mixing too much things out of core ideas of Linear algebra, which leads to confusion.
