The Khan Academy is brainchild of Salman Khan, who brought the idea of educating young people, self-starters, people who learn at their own pace -- online. The educational startup now counts over 2,600 videos in its library, with sessions or classes on everything from arithmetic to physics, including 211 practice exercises, to let students watch videos and learn at their own pace.
Khan just announced that the platform is seeing 39 million pageviews and 3.5 million unique users per month. That 3.5 million unique users is up 309 percent year-over-year. Khan Academy's free lessons have been viewed more than 82 million times on YouTube.
