See,

College is unlike lower education, in that you aren't there to merely learn - you're there to contribute to the greater body of human knowledge.

Gen Ed courses will likely lack an engineering approach to their problems. You have expertise that you can offer to enhance the content of those courses. Maybe an anthropology teacher has too much data and not enough time. Maybe a business professor knows the equations that need to run, but sticks to the old habit of writing them out by hand. Change these things!

You'll learn along the way, sure. But the POINT is to contribute. And that's where a diverse education is fundamental to our society.
