The Duke of Cambridge has visited Oxford to see the results of three major investment projects in the city.
Prince William was given tours of Magdalen College's Longwall Library, the Weston Library and the Blavatnik School of Government.
He officially opened the two new libraries and met students at all three locations.
The duke last visited the city in 2014 to officially open the new Dickson Poon China Centre at St Hugh's College.
During his visit to Magdalen College the duke confessed he was a lazy student while studying at at St Andrews University.
He told the students: "I can't say I was a regular attender of libraries."
The prince made the admission as he spoke to students who were sitting at desks - but he was quick to realise they were not really studying hard.
Jack Barber, who is reading history at Magdalen College, said William spotted that his book had been placed as a prop for the visit.
The 21-year-old said: "He saw my book and it was obviously the first one I plucked off the shelf. He said 'Enjoy your pretend studying'."
