From Hogwarts to Brown

Daniel Radcliffe, Rupert Grint, and Emma Watson have played Harry Potter, Ron Weasley, and Hermione Granger, in the entire Harry Potter film series, based on the books by J. K. Rowling. Of the three, only Radcliffe had previously acted in a film.

The three Harry Potter stars have varied educational backgrounds.  One attended an Ivy League University.

Emma Charlotte Duerre Watson (born April 15, 1990) was cast as Hermione at the age of nine, having previously acted only in school plays.   According to Wikipedia, Watson attended The Dragon School, an independent preparatory school, until June 2003 and then moved to Headington School, an independent school for girls, in Oxford.   While on film sets, Watson and her peers were tutored for up to five hours a day.   In June 2006, Watson took GCSE examinations in 10 subjects and received straight-A exam results.  Then in 2008, she received A grades in all her A level examinations.   Watson took a gap year to film Harry Potter and the Deathly Hallows and is currently enrolled at Brown University in Providence, Rhode Island.

Daniel Jacob Radcliffe (born July 23, 1989) was educated at two independent schools for boys: Sussex House School, a day school in Cadogan Square in Chelsea in London, and the City of London School, a day school in the City of London, where he studied for AS levels.  According to Wikipedia, he achieved A grades in the three AS-levels he sat in 2006, but then decided to take a break from education, and did not go to college or university.

Rupert  Grint (born August 24, 1988) attended St Josephs Primary School in Hertford, prior to enrolling at Richard Hale School, a boys’ state comprehensive school in Hertford, the county town of Hertfordshire, followed by the Top Hat Stage School, also in Hertford.   According to Wikipedia, in July 2004, Grint finished Richard Hale School, taking his GCSE examinations.
