I am a high-school student from Shanghai, China. I love singing, math, computer science, and watching cat videos. Recently I've been watching digital SAT preparation videos on Khan Academy. I've been watching Mr.Khan's math videos for more than ten years. I would like to join this community both to learn and to teach. I feel like I've owe Mr.Khan a lot. He taught me more math than anyone else in the world.
