Is is appropriate if I water down rocket science down to "Rocket shoots water out one way, rocket goes other way"? In actual seriousness, is your focused track in Astronautics closer to that of a minor or dual major? I took a minor in mechatronics when going for a bachelor's in mechanical engineering which was ironically tougher than my actual major (mainly since my teachers for my minor were more serious/BS graders than those in my major).
