I did ChemE for undergrad and aerospace focused on systems engineering for postgrad so that colored my experience a bit. The former was brutal and the latter naturally collaborative with a bunch of projects, so we all worked together.

The postgrad continuum mechanics class (I think taught by the geophysics department?) was the biggest exception so I’m betting there’s quite a bit of variance among fields.

I don’t doubt there’s academic fraud (living in the dorm my first year wiped away any illusion) but within my major it didn’t end well.
