I believe that’s: once a student “registers” and begins to use the tool, the college can supply questions. I simply can’t imagine an adcom for a competitive college having time to respond personally. They’re already on the go all year long.
There are automated ways, including scanning for keywords, that could be used to shoot back auto questions. I’m imagining generic. The “materials” in the portfolios that trigger the questions could be categorical, eg, he added a sample essay, he gets thinking points back from the college. Not personalized editorial remarks. Much like my fitness site knows I checked their knee exercises and now keeps sending me new bits about knees. Same as online marketing works.
Wait and see. We don’t know yet.
This part is just a tool.
