It's the last episode of Skillset’s Season Two, our masterclass on high school movies. But I can’t throw my graduation cap before I get to talk about three of my all-time favorite flicks. First up, Bring it On introduced us to the crazy world of high school competitive cheerleading. But it turns out some of those insane moves -- okay, a lot of them -- aren’t technically legal. So how real is Bring it On? We ask Susie Knoblauch of the National Federation of State High School Associations who oversees cheer battles to separate the truth from the tinsel. Then, we talk about the most famous prom dress in movie history. Hint: It’s pink. It’s covered in blood. It’s Carrie’s, and costume designer Luis Sequera had the tough job of updating the iconic gown when Hollywood remade Carrie 37 years after the original. That’s several lifetimes in teenage trends. And finally, let’s go to Harry Potter’s Hogwarts where the class subjects are fiction, but the teaching styles are all too real. There’s good teachers and bad teachers, boring classes and classes that should be interesting but somehow still wind up boring because the teacher doesn’t care. Dr. Melissa Johnson of Virginia Commonwealth University studied their teaching styles and discovered who is the worst teacher at Hogwarts -- and it isn't because they tried to kill their students.Skillset will be back in early spring with our third season and a new theme. We’ll be traveling around the world in eight episodes, so subscribe to the show on your favorite podcatcher and join us for a new adventure and a new batch of experts.
