Im going to university next year

Hi, im in my last year of highschool studying general sciences, leaning more into engineering. Ive had a silly dream of making a functional exo-suit. I know that it takes alot of work mechatronics and robotics and whatnot. The uni im going to promises a diploma in 5 years. So if i study both robotics and mechatronics ill have earned 2 diplomas at the cost of 10 years. My goal is to work in a field where good money is promised, and something that can help me leave my country asap because im in a 3rd world country with not so many jobs. I know that what im saying might sound confusing but im stressing out as i only have a few months left to decide what to do.
