The secondary school Tyson attended was Cambridge International School, a private school. He attended until he was fifteen when his father had him moved to Cambridge University, four years early.
His father was able to do this because he’d held a position at Cambridge University as a Professor of Mathematics for over twenty years.
At Cambridge Tyson studied mathematics and military history. His anti-war father disagreed with his choice of minor but agreed to let him continue it rather than taking political studies. Tyson was also able to study law at Cambridge for half a semester when he finished mathematics early.
