Or another way to look at it: If you try to take the ~135 engineering credit hours in the same four years that L&S majors take 120 credits, you're not going to be able to put 100% into every assignment in every class. So, some will be "good enough" (B-, C+, solid B?) even though you might have been a "curve wrecker" in high school. Maybe the required "breadth of knowledge" classes in public speaking, sociology and global studies will kill your GPA. Even if public speaking helps you give presentations later on, you might compare unfavorably with the pre-law and poli sci students. Maybe the global studies prof prefers his own opinion regurgitated back at him to competent independent thought...but it took you a semester (and bad grade) to discover that.
Same as in your "real" job...some people reward you for good results, but others have an agenda.
