Khan Academy is maybe one of the greatest tools I have for learning as a college student in todays world. I had a math teacher who told us about it my freshman year of college and ever since I have used it to learn about algebra, trig, calculus, physics, chemistry, biology, logic, history, art, computer programming, and the list could go on. The best part about this idea for education is that its built for any age group. A third grader could get on there and learn about anything they wanted. Salman Khan has really pushed the envelope for free education and this idea that you can learn anything is really inspiring as a student and as a person who struggles to keep myself focused on one area of study or interest.
