They are being so vague that’s it’s impossible for us to know, but they didn’t say “at scale”. You’re certainly correct that there isn’t some secret sauce that we could just apply to everyone. But it wouldn’t surprise me if there was a service that costs (high) 5 or 6 figures per year that could substantially increase test scores.
Though I would imagine such a service would have to take place over months/years and not days/weeks, and that kind of blurs the lines of whether it even counts as test prep at that point.
