The strong example set by her sisters may be one reason behind her success. Her older sister Anne-Marie, 18, is the youngest person to have passed A-level computing, at 11, when she also passed pure maths. She went on to study maths at John Hopkins University in the United States at 13. Another sister, Christiana, began undergraduate studies even younger, at 11.
When The TES spoke to Samantha last year, she confessed she preferred to prepare for maths exams by playing Monopoly and Connect Four and filling in sudoku puzzles, than by scouring text books.
"I find maths like a big game. Other people think it is a problem, all numbers jumbled up, but they don't know the meaning," she said.
Since then, Samantha has been awarded a scholarship to the independent St Joseph's Convent School in Reading, Berkshire, and found time to write Maths Manual, a collection of revision notes designed to help young children take GCSE early. It has already helped her younger brother and sister, twins Peter and Paula.
