Eyecatcher from Episode 4 of You-zitsu (TV) said that the ranking up (promotion) in S-System is collective. You're right about thinking it like the premise at Baka to Test.

I know it's easy to do now that we have very few characters to take note. However, in the long run, if all D-Class students are to be promoted at C-Class (and to A-Class for some time), not only we re-categorize each article devoted to them but also those that are being displaced one-by-one.
