I know you're first comment is said in jest, but I found at school that whilst maths/physics/chemistry teachers would push science and their own subjects, when it came to picking an engineering subject at university they were of very little help.
Same with me. I was good at maths and physics at school so ended up doing a degree in mathematical physics.
Never really even considered any sort of engineering as an option.
I've actually ended up being a software developer now, and even though I used to write programs myself back then I never really considered computer science either. It was all just about carrying on with one of the subjects I did at A-Level.

Further maths would defo have boiled my brain a bit thinking back - I did chemistry.
