It’s hard to argue with the premise that you get what you pay for.
However, sometimes a very valuable resource comes along that doesn’t cost a thing. The Khan Academy is just one of those valuable resources that won’t cost you a penny.
What started as an uncle creating math tutorials via YouTube for his family has turned into a major hub of educational content. Check out the videos and create an account to track your progress. (Note: you must be at least 13 years old to create an account.)
Free education at your own pace? Sounds like a lot of value for no money. Kudos Khan Academy.
