Harry Potter fans are in for a blast. The Portkey: A Harry Potter Fan Fest organised by Vagabond has a list of events that even ardent fans, Potterheads, will have a tough time finishing. For starters, they can quickly think of their quiz partners while brushing up on Potter trivia. Because The Nastily Exhausting Wizarding Tests (NEWTS), the organisers say, is the ultimate Harry Potter quiz. There are, after all, prizes to win.
