11. Prince Harry
After attending Eton College, an independent boarding high school in the U.K., Prince Harry took a gap year to work on a cattle station in Australia. In 2005, the Duke of Sussex enrolled in the Royal Military Academy Sandhurst, where he moved up the ranks and was eventually promoted to the lieutenant level. William’s younger brother Prince Harry also graduated from Eton; Harry does not have a university degree but completed ten months of officer commissioning training at Royal Military Academy Sandhurst.
