My name is Hermione Granger-Nott, although most know me only by my adoptive parents" name, Granger. I have recently left Hogwarts School of Witchcraft and Wizardry, partway through the first term of my first year, and consider this a wonderful oppurtunity to pursue better education, such as at your fine school. I have of course appropriately researched your admissions procedures, and feel that I am quite up to the task. For your convenience I have signed this letter with an ink-print of my Nott family ring, which I hope is adequate proof of my blood status; I will of course bring the ring itself with me when I travel to your school, but I do not trust such a valuable heirloom to owl post. I am prepared to take the placement examination at any time that you would consider to be appropriate.
