Khadijah Niazi overcame several barriers to finish her introductory physics exam online. Pakistan recently blocked access to YouTube, the site Udacity used to host its lessons. She posted a plea for help on a Udacity message board and several classmates from Malaysia, Portugal, and England attempted to find a workaround. The next day she took the final exam. Even more amazing than the technology know-how is the fact that Kadijah was 11 years old and aced the class with the highest distinction.
