Khan Academy

Being a non-profit organization, Khan Academy aims to provide a free and best education for anyone and anywhere in the world. It was started in 2006 by educator Salman Khan. The site provides micro-lectures, instructional videos, and practice assignments to help you develop and sharpen your skills. They have partnered with other post-secondary schools and offer a well-organized interface. What more, almost every course you find on this platform is for free.

Khan Academy focuses more on traditional subjects like mathematics, science, humanities, economics, and computer programming. This learning platform provides you with a personalized learning dashboard that empowers the learners to study at their own pace in and outside the classroom.
