One user says, "I spent the first 15 years of my life failing school. When I was 14, I started failing pretty badly and fell into a world of drug addiction. The final exam of high school that determines if you go to University or not was coming, and I had no idea what to do. I first met the Khan Academy in 2007. With 5 years of work to catch up on and only Khan Academy helping me, it was a grueling experience. Thanks to Salman Khan, he has allowed a drug addict whom the public would look down upon to persevere and come out on the other side with a result good enough to get into Western Australia's best University."
