Midyear transcripts

Hi,

I applied to Amherst College, University of Southern California (USC), and Boston College this year all for regular decision. Although I think it’s implied that all 3 want my mid-year transcripts (first-semester senior year), Amherst College was the only school that specifically asked for it in the application portal, whereas USC and Boston College didn’t.

Do all 3 of these schools want my mid-year reports? And do all regular decision applicants, by definition, have to submit mid-year reports?
