Oscar Wilde did well at school, but he did still better at college, where the competition was more severe.

He entered Trinity on October 19th, 1871, just three days after his seventeenth birthday.

Sir Edward Sullivan writes me that when Oscar matriculated at Trinity he was already "a thoroughly good classical scholar of a brilliant type," and he goes on to give an invaluable snap-shot of him at this time; a likeness, in fact, the chief features of which grew more and more characteristic as the years went on.
"He had rooms in College at the north side of one of the older squares, known as Botany Bay.

These rooms were exceedingly grimy and ill-kept.

He never entertained there.
