I started off looking to 'do one one of the subjects I did at a-level' as a degree. That would have been Maths, Physics, or Design Tech, and I didnt really want to do any one of them. So for me, as soon as i had the idea of doing mechanical engineering and started looking what that was, and how it tied together my ability to understand maths and physics but also the fact I enjoy designing and making mechanical things, it made perfect sense.
Message me if you want to talk in more detail as I am not on here very often, but while I am sort of biased, I have not looked back at all and am really glad I have gone down the route of mechanical engineering as I really enjoy the work, which I have also found easy to find.
