All in all I think we agree.
Wrt sequential - it’s understandable /normal not to know what that means in terms of curriculum design and it seemed you were unclear about it, insisting Kelley isn’t sequential when the curriculum design has been explicitly (and with maaaaannnyyy leeeeeegthy discussions) decided to be so. There’s no indication whether you’re a student, faculty/administrator, parent, or Kelley graduate. Didn’t mean to offend but assumed you were part of the 98% who don’t know because they don’t have to !
Calculus isn’t for use (as you said, they have quants for that). It’s a signifier for certain firms and certain types of jobs.
