Filmmaking taught by Martin Scorsese? Comedy taught by Steve Martin? Chess taught by Garry Kasparov? Tennis taught by Serena Williams? Cooking taught by Gordon Ramsay? If that sounds like some sort of fantasy school for famous expert tutors, you would be partially correct — except for the fantasy part. MasterClass is an online platform where well-known masters of their trade serve up their expertise to Joe Public. For an annual fee of $180, you can access all classes through the web or mobile app, or pay a $90 one-time fee for access to an individual class.
