There is really no back story to this one.
An alternate universe where Celestia sends Twilight to Ponyville a lot earlier in her life, so she has to attend the local highschool. Not everypony knows that she came from Celestia's School for the Magically Gifted (CSMG) but those who do give rather mixed results. Gonna be pretty slice-of-life-y and it's not very serious, just an idea I wanted to get out.
Because this has never been done before, right?

I do NOT own MLP or FiM or anything else that Hasbro or Studio B owns, the only thing I own is this story, not even the characters in it, mkay?
