Usando o termo estudante liberalmente temos o caso de Angus Buchanan, um aborto. Ele nunca foi realmente um verdadeiro estudante de Hogwarts, em que ele nunca recebeu a carta, mas ele conseguiu chegar tão longe quanto o Chapéu Seletor, então ele foi um estudante em que ele chegou a Hogwarts. Uma vez na escola, o Chapéu revelou por todos que ele era um aborto e assim ele partiu. Novamente, não está totalmente claro se ele foi formalmente rejeitado da escola depois de nunca ter sido formalmente um estudante ou se ele deixou por conta própria.
By the mid-nineteenth century the Buchanan family comprised an overworked mother, a fierce father and eleven children. The household was loud and chaotic, but even so, it is surprising that neither of the Buchanan parents realised that their third son, Angus, was a Squib – a wizard-born child with no magical powers. [...]
His brothers and sisters were all very fond of Angus, who was the largest and kindest of them all, so they covered up for him in front of his parents. The deception was innocently begun, but as the time approached for him to leave for Hogwarts, Angus and his siblings became uneasily aware that they could not maintain the pretence much longer. No letter from school arrived for Angus, but his panicking sister Flora forged one, which kept the parents in ignorance for several weeks more. Shy, good-natured and frightened of his father, Angus could not think of any alternative but to play along with his older siblings. They took him to Diagon Alley, where they bought a wand and pretended that it had chosen him. On the appointed day, his big brother Hamish took him to Hogwarts on the back of his broomstick, hoping against desperate hope that Angus would be allowed to stay once they got there, or that the school might be able to tease some magic out of him.
It had never happened before and it has never happened since, but Angus got as far as the Sorting Hat before he was exposed. In sheer desperation he threw himself ahead of a girl whose name had been called and placed the Hat upon his head. The horror of the moment when the Hat announced kindly that the boy beneath it was a good-hearted chap, but no wizard, would never be forgotten by those who witnessed it. Angus took off the hat and left the hall with tears streaming down his face.
News of Angus’s humiliation reached his parents in a flurry of owls before their son arrived home on foot. He was met by his humiliated father, who barred his entrance, bade him never darken their door again, and fired curses after Angus as he fled.
Outra declaração não clara é a seguinte: "Nunca aconteceu antes e nunca aconteceu desde então". Isso poderia significar que um aborto nunca chegou tão longe quanto o Chapéu antes de ser exposto ou o Chapéu nunca rejeitou ninguém antes. Se este último, então este é o melhor exemplo que temos de um estudante não ter sido classificado antes ... em Hogwarts, isto é.
