Prince Harry was never blessed with brains, but fortunately these aren't necessary as a member of the Royal Family. Even if a job can't be secured from a well-heeled family friend there is always the option of military service, after greasing a few palms, and awarding a few medals to the right people.
Most recruits to Sandhurst are graduates, but occasionally recruits are admitted with lower qualifications, especially if their surname is Windsor. In Harry's case, he was admitted with just a grade B in art, and a grade D in geography - the worst results of anyone in his year at school.
Unfortunately however, Harry wasn't even bright enough to manage Art. One of his former teachers at Eton claims she was asked by a senior master at the school to help Harry complete his coursework.
If found to have cheated Harry could face expulsion from the Army. Fortunately the Windsors are quite adept at manipulating the results of investigations. Expect to see this one buried, like the rest, and a collection of chinless wonder military types to crop up on TV saying what a top officer he is.
