Emma Watson, best known as Hermione Granger of the Harry Potter movies, posted a "cap and gown" selfie on Twitter Sunday, sharing that she graduated from the Brown University with a bachelor's degree in English literature.

The "Noah" star started her freshman year at the Ivy League school in 2009, but took a break in 2011 to film the final movie of the Harry Potter franchise - "Harry Potter and the Deathly Hallows, Part 2." In 2009, Watson was named the "highest-grossing actress of the decade" by the Guinness Book of World Records, Penn Live reports.

The open curriculum at the Brown University inspired Watson to choose the Ivy League School in Rhode Island among other prominent higher education institutions in the world. The freedom to select majors and pursue independent studies on subjects unrelated to the curriculum was another factor that attracted the actor to the Brown campus.

Watson was apprehensive about returning to college after gaining world-wide celebrity status.

"On the first day, I walked into the canteen and everyone went completely silent and turned to look at me. 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,'" Watson said, EOnline reports.

Contrary to her apprehensions, the Harry Potter starlet led a normal student life at Brown. She was never asked for an autograph and nor did any student post pictures of her parties on Facebook.

Watson spent her junior year studying abroad at the Oxford University, in her native - England, Bostlnno reports.

During her college years, the 24-year-old actress filmed the final two Harry Potter movies and acted in movies outside the franchise like "The Perks of Being a Wallflower," "This is the End," "The Bling Ring" and Darren Aronofsky's Biblical epic "Noah."

The British actress now plans to complete filming of the thriller "Regression", co-starring Ethan Hawke, and invest more time to pursue her other passions like sports (field hockey, tennis and netball), dancing (break dance and contemporary) or being close to nature and animals.
