I am a bad student, so I was happy to find out about Khan Academy. However, it felt like such a drag because I didn't get anything back. Can you guys add a special type of badge (or whatever you wanna call it) for when I finish a unit and certificates for when I finish a course? It motivates me when I finish something and my parents give me a badge or a ceritficate. It just feels...rewarding.
How can we help?
