London, Oct 18 : `Harry Potter' star Emma Watson has resumed her studies after starting classes at Oxford University. Watson, 21, best known for playing studious witch `Hermione Granger' in the hit franchise, is a student at Rhode Island's Brown University but has been transferred to Oxford's Worcester College for a year abroad. She has warned fans in a post on her official blog published on 16th October that she'll be out of the spotlight for a while as she continues her English literature classes. "To Everyone who is starting a New School Year, (sorry those who have been at school for a while Oxford starts late)," the Daily Express quoted her as posting on her blog. Just to say have a great term and good luck with all your work. You might not hear from me for a while because I will be really busy studying but I wanted to just say hi and bye... Love Emma xx," she added. (ANI)
