The School For Good And Evil~ FanFiction

Every four years the school for good and evil chooses two readers to come into the school for good and evil, this year there are three. Why? Sophie had always dreamt of going to the SGE ever since she read a book in the library about it. Agatha didn't believe it at all, "that's stupid" she laughed. Sophie wrote a letter to the school on why she should be accepted to go there, and put it in the wishing tree where Sophie and Agatha first met. Agatha and Evelynn were the chosen two readers, but since SGE received Sophie letter they decided maybe three readers this time.
"Three?!" "There are never three!" Lady Lesso exclaimed .
"This year there will be, Agatha, Sophie and Evelynn" The headmaster addressed
"Ok, well what schools are they going to?" Professor Dovey asked
" Evelynn and Sophie will be in evil, Agatha will be in Good." the headmaster stated

Sophie and Agatha were best friends in the town of Gavaldon. They knew Evelynn but were not close, that type of person you'd just say hi to when walking. The girls were confused. Why did the school choose them, what does it mean?
