I strongly support Duncan Michael's view that not all good engineers need A Level maths. I managed to get into university with an E in A Level maths.
The maths which I have used in the subsequent 25 years has been primarily algebra and trigonometry and I would not deny that the A level course developed my skills in this area.
Just about everything I managed to learn in the university maths class has long since been forgotten, with the exception of numerical maths which provided a grounding in computer programming.
My other two A Levels were in physics and geography, both of which provided a much better grounding for my subsequent career.
