Ha, good plan. Which engineering degree depends on what turns you, what you are good at (math?), what kind of sat-diving you are keen on, and where you want to work and live and what you want to do after your diving career. Civil, structural, mechanical, petroleum, etc..... Many engg curriculums are similar for the first year or so, so switching around is possible mid-stream Take a close look at the courses and foci of the engg schools you are considering; they may say (for example) Civil Engineer, but when it comes down to it they focus on roads, or commercial buildings, or bridges, or something.
