@Neenie, we don’t know, but it would be very hard to accumulate much of that in one semester in college, though admitted general engineering students have up until the end of their sophomore year to apply be accepted, and declare their major. On the application, they may list their HS achievements as well, and there is an essay where they must state succinctly their career goals and why their chosen major will get them there - To show that they have really considered their path, which is good in that it should reduce jumping majors later when it will more likely reduce their chances of graduating on time.
