Sorry for the late reply. Meta trails is a companion to tools like Codeacademy or Team Treehouse. What we've found is its really hard to answer questions like 'Do you know CSS' its much easier to ask smaller questions like can you postion an element on a page, can you style typography correctly. By asking these smaller questions you can gauge where you are and whats missing. Meta Trails asks you those questions, its more of a tool than a platform.
