Oxbridge graduates are cashing in on the "massively growing" demand for private tutoring to ensure children win places at top public schools.
An increasing number of agencies charge up to ??70 an hour to prepare children for the common entrance examination at schools such as Eton and Harrow.
One such is Bright Young Things, set up in London`s Notting Hill in 2007 by 23-year-old Oxford biology graduate Malachy Guinness.
He says: "You do not need any official qualifications, so families look for very good degrees, quite often from Oxbridge."
He describes how exotic holidays are sometimes part of the tutoring package, including skiing trips. He says: "I have just come back from New York, where I spent a month coaching a child for the Eton entrance exam."
Will Orr-Ewing, 24, another former Oxford student, set up Russell Group Tutors three years ago, which he describes as "a good way of making money".
He says: "Tutoring works really well as a business. Five or 10 years ago it was seen as a shadowy industry that schools hated, but now it is a legitimate business option."
