Hollywood actress Emma Watson enrolled herself at Brown University in 2009 and dropped out to finish the final "Harry Potter" movie. After almost five years and three enrollments to the university, the actress finally accomplished a degree in English Literature.

According to the Web site the fact that Emma Watson brought a police officer with her to the ceremony is "a marked contrast with her stated aim of having a 'normal' experience as a student at the elite U.S. college." Also, Watson's mother Jacqueline Luesby was present at the ceremony to witness the proud moment.

"On the first day, I walked into the canteen and everyone went completely silent and turned to look at me," told Emma Watson to Sunday Times (via Us Magazine).

"I had to say to myself, 'It's okay, you can do this. You just have to take a deep breath and gather your courage,'" added "Noah" actress.

Emma Watson also posted a photo of her from the graduation day on Twitter.
