The A Levels I did were Maths, Physics, ICT and Product Design…….I got BCAB for those!
To get onto an engineering course at uni, you generally have to have done A Level Maths and some uni’s say physics too!
If A Levels aren’t you cup of tea, there’s also apprentiships and courses at college which you can do 🙂
I did Maths, Physics, Biology and French. I definitely recommend Maths and Physics, both of those are used a lot in engineering. I would also recommend doing one of the essay subjects on top of those two (e.g. a language, english, history etc). It is really good to be able to show people you are capable of both science/maths subjects and literary subjects, even beyond your degree! I still mention my French A level even today.
