How to cheer up a friend after they failed their exams?

My friend failed her exams and she seemed really upset yesterday but I'm not exactly the empathetic kind so I didn't really know what to say other than remind her of her chance to do better in the resits and she seemed even more upset at that? :/ I'm meeting her for drinks & a movie tonight so what's something I can do or say to brighten her mood?
