Back in November 2000, Judith Keppel became the first contestant to win the top prize of £1,000,000 on hit quiz show Who Wants To Be A Millionaire.
It took eight series' of the UK show for someone to grab the ultimate prize of £1m - which was secured by garden designer Judith from Fulham.
She later appeared on the show again in 2003 and scooped a further £32,000.
Although the questions start simple, they get increasingly harder.
Here we have created a quiz to test whether you could have joined Judith in winning £1m by answering all 15 questions correctly.
Judith actually had it slightly easier as she had her lifelines - phone a friend, 50/50, and ask the audience.
Give it a go and see if you have what it takes!
