Narayan is an average class VIII student, but his grades fail to impress his teachers because his grasp of mathematics always left him high and dry. But today he has what he calls an online guru the 'Khan Academy', which he refers to dedicatedly about an hour a day, five days a week. This not only helps him understand at ease what he couldn't at school, but he is also ahead of his class.

The home page on www.khanacademy.org greets you with a black-board like YouTube video which gives you the overview of how it works, and to sum it up, I can also say that I spend 20 minutes glued to the screen with the French Revolution, Le Chatelier's Principle and algebra. The idea is simply awesome and unlike a realtime class or a tutor, you have the flexibility of revisiting any frame you missed. Voila!! Simply awesome.

So why did Salman Khan, a computer science major decide to spend his time and energy in creating educational videos which cover topics from algebra, biology, history, and even physics? It began when he was teaching his cousin Nadia a little mathematics with conference calls on Yahoo! Doodle. He soon posted a few videos for her and her friends and found that several other people had checked his videos. Thus began his journey into online-education with Khan Academy, a not-for-profit organization with the mission of giving access to knowledge to anyone, anywhere.

The Khan Academy on YouTube (www.youtube.com/khanacademy) gets as many as 2,00,000 unique students every month and has more than 63,510 subscribers since November 2006. Not only that, there have been more than 19,344,909 total upload views.

Salman, who quit his day job as a hedge-fund analyst, has an MBA from Harvard Business School. He also holds a Masters in electrical engineering and computer science, a BS in electrical engineering and computer science, and a BS in mathematics from the Massachusetts Institute of Technology.
