Good question! I certainly couldn’t do my job without the science and maths and other things that I learnt at school, college and university. But engineering is all about teamworking and problem solving which you can’t really learn that in classroom – if I couldn’t do them then I wouldn’t be a very good engineer!
So things I’ve learnt in my normal life, like getting along with friends and finding solutions to any sort of problem, have been really usefull too!
Most every job ad you see for engineering jobs (have a try at google with “engineering jobs” and look at some adverts to get an idea) say you need a “good degree in science or engineering”, that’s fairly essential. Degrees – for better or for worse – are the key to many doors, but in terms of engineering the one you get is important!
Like the others have said, if you want to be ‘an engineer’ then a degree, or similar high-level qualification is going to help, although there are apprenticeship schemes and the like that can also work. Science and maths will help you get there.
Probably the most important step, though, is to find something you really enjoy and do it as much as you can! That way the learning and exams are MUCH easier. I love science and mechanics and engineering, so spending years learning about it was great…most of the time…some of the exams were still really stressful 🙂
