You are arguing contrary to fact because I have actually seen it happen.
OK thanks for the advice everyone! At this point I’m leaning most towards mechanical engineering, because it’s flexible I’ve heard it’s a great base for a masters degree.
Most engineering programs are nearly identical in the first year, so keep in mind that you don’t have to make the choice right away.
