Americans left stuck at home turn to online learning

Dahwal Shah runs a site called Class Central, which he describes as a 'Trip Advisor' for online courses offered by top universities worldwide. 'As soon as the U.S. went into lockdown last Sunday, we saw a huge surge in traffic,' Shah said. The site lists thousands of Massive Open Online Courses, also known as MOOCs. The vast majority are free. Many courses require hours of online class time and can take a month or longer to complete. But if you're looking for a source of meaningful self-improvement, the options are endless.
