Pros
Pro Free
Both edX and the classes are free.
Pro Offers courses from well known schools
edX offers courses from a wide range of well known colleges and universities including Harvard, MIT, UC Berkeley, Cornell and more.
Pro Large selection of science courses
edX offers a wide variety of science-related courses. This makes it a great resource for learning not only specific programming languages, but also other topics relating to computer science.
Pro A lot of topics (subjects)
Topics include biology, business, chemistry, computer science, economics, finance, electronics, engineering, food and nutrition, history, humanities, law, literature, math, medicine, music, philosophy, physics, science, statistics and more.
Pro Offer certificates for some courses
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.
Cons
Con Lack of engagement in the forums
edX does not have the same forum participation from both students and instructors that other websites do, and the form of engagement often does not encourage discussion.
Con Courses aren't always available
While edX does offer some self-paced courses, you may end up waiting for the course of your choice to be run.
Con The forums are difficult to navigate
The forums are difficult to sort by date and topic, and are unintuitive to navigate.
Con Too much "Polynomial vectors"
He's mixing too much things out of core ideas of Linear algebra, which leads to confusion.
Con Teaching skills need to be improved
