Ha! I didn't get my degree in engineering, but most of my friends did and this describes many classes they took in their field. Especially applied engineering physics.

I had two friends in AEP that were problem set partners, and they spent so much time working together her now-fiancé didn't ask her out for ages because he thought her problem set partner was her boyfriend.

And no, these kids were not dull buds. The girl is currently a grad student at MIT, and the not-boyfriend problem set partner is a grad student Harvard.
