Advanced Diploma In Insurance
  
Simply, this is a certification for the supreme life of any party: a British insurance salesman.
Sure, Nigel lacked even average looks, personality, and family wealth, but he was good at math and had enough quid to pay the Chartered Insurance Institute (CII) in the United Kingdom for the right to take an exam and get his Advanced Diploma in Insurance. After that, he was allowed to pursue more specific accreditations from the Fellowship of the Chartered Insurance Institute (FCII), such as Chartered Insurance Broker, Chartered Financial Planner, and so forth and so on.
