well you can't just take engineering classes willy-nilly, you usually go through intro/orientation classes, necessary prerequisites and corequisites classes. You can't really minor in engineering, so if you're a science major and enjoy application-based and interdisciplinary classes, engineering science is a good option. The major has the classic science classes built into the curriculum, so it's a really efficient way to pursue both engineering and pre-professional studies. Just throwing it out there if anyone is wondering about their options.
