Watson, 22, was previously enrolled at the Ivy League college from September 2009 to March 2011, at which point she decided to take a short break from her studies to focus on her career and to promote the final installment of the Harry Potter franchise, which came out in July of that year.
"As you know, I love Brown and I love studying pretty much more than anything, but recently I've had so much to juggle that being a student AND fulfilling my other commitments has become a little impossible," the Brit wrote on her blog at the time.
"I will still be working towards my degree," she assured fans. "It's just going to take me a semester or two longer than I thought."
A few months later, the Perks of Being a Wallflower star announced that she would be spending her junior year abroad, at Oxford University. While there, she met fellow student Will Adamowicz, whom she has been dating since late 2011.
Watson had planned to return to Brown once she returned from her year in England, but she deferred again in August to take on a number of film projects, including the Sofia Coppola-directed flick Bling Ring and Noah, starring Russell Crowe as the biblical title character.
Now, however, it seems she's ready to once again step out of the spotlight and into the crowd of co-eds at Brown.
"I've never even been asked for an autograph on campus," she told the Sunday Times Magazine last year of her experience at the school. "I threw a party for nearly 100 students and not a single person put a photo on Facebook."
