A Hogwarts education just wasn't enough!

Emma Watson has started her junior year at Oxford University in Oxford, England. The Harry Potter star posted a note on her blog to let fans know she'd be MIA from the public spotlight and focused on school for the next few months.

"You might not hear from me for a while because I will be really busy studying, but I wanted to just say hi and goodbye," the 21-year-old wrote.

Watson is still enrolled at Brown University; she's just spending her third year studying "abroad" in her native country. "Then I'll return to Brown to complete my last year," she explained to the Virginian Pilot in July.

"Hope you all like My Week with Marilyn," she added. Watson plays a wardrobe assistant in the Marilyn Monroe biopic starring Michelle Williams as the late screen goddess. "I'll keep you posted on [The Perks of Being a Wallfower]!"

The actress told fans who were also in school to "have a great term" and wished them "good luck with all [their] work."
