Ludicrous Listener

Ludicrous Listener is a Sun Badge given for watching 10 hours of video in a single topic. When earning this badge, you get 50,000 Energy Points from the videos you watched, depending on the length of the videos watched. No free energy points are given. This is one of the many badges you can earn on Khan Academy.

This badge is obtainable by watching all the Chemistry, Crash Course videos, SAT Test prep or Talks and Interviews. It is very hard to get because most of the videos are too short.
