Prince William is commuting to school just like any other student.
The 31-year-old royal, who is attending the University of Cambridge for a 10-week-program, traveled by train for his first day of classes on Tuesday, Jan. 7.
Kate Middleton's husband, clad in a navy suit and mahogany tie, took the 9:44 a.m. train from Kings Cross station in Central London, a source reveals exclusively to E! News.
"He didn't travel first class, and blended in pretty well as a commuter," the source said. "He kept himself to himself and was just reading."
No word if he was reading from a textbook and preparing for his course work.
After his first day, an eyewitness spotted William returning to London on a 5 p.m. train.
For his second day on Wednesday, Jan. 8, William was spotted catching a 9 a.m. train at Kings Cross and opted for less formal attire after dressing up for his first day.
"He was dressed down in a baseball cap, and although a few people did double takes, he didn't draw attention to himself," the source said of William. "He seemed quite comfortable and relaxed and was only bothered about getting on a train like everybody else."
Sounds like every other person, in any metropolitan city, who has to make their way inside a train during rush hour.
The executive education program of seminars, lectures and meetings "will draw on the strengths of academics across the university," according to a palace press release. It started in early January and will run until mid-March.
The course has been designed help provide Prince George's dad with "an understanding of contemporary issues affecting agricultural business and rural communities in the United Kingdom."
