Hey Ghengis you must be younger than I thought! When I was at Grammar School, Northern Universities Joint Matriculation Board Syllabus 'B' introduced us to differential calculus in the fourth year. A great boost when we moved on to integration of multiple trigonometrical variables on the Ordinary National course when I was an electrical apprentice. I always knew that standards were dropping, but differential equations definitely aren't in any university syllabus that I'm familiar with either.
