Flute Criteria question?

I just finished my freshman year of high school and I've been playing the flute for two years now. I'm going to a camp this summer (que nerdy band geek comments) and one of my friends mentioned the "12 major scales." My teacher has never taught me those and I was wondering what exactly is expected of me. At my level, am I supposed to know these scales? What are flutists' of my level usual ability?
