Hey! I didn't do this myself but know people that have. I would definitely recommend you go for it, there's lots of roles so you can explore both engineering and finance and you'll gain practical experience. That'll look great when applying for uni/jobs etc and shows you're actively looking to learn and gain experience. I cant speak too much on the difficulty, I imagine parts will be challenging but overall it shouldn't be impossible. The people I know that have done it had a lot of fun
