When I was referring to CommonApp, I didn’t mean to also include along it’s heavy fee per application. Beyond the medical field and lawyers, what other fields do you believe that qualifications is a solved problem? Mind that a certification itself can also be cost prohibitive — that’s ok if it can be amortized over many apps though.
