Could you build this?

Partial The app shell, quizzing, and practice-round flow are easy to build with AI. The product's value depends on expert-written scenarios and rationales that only experienced product designers can produce.

What it would actually take: The stack is a standard web app with a question bank, scoring by skill dimension, and spaced practice. The hard part is the content: a large set of realistic product decisions with expert answers and reasoning, reviewed by senior designers. Calibrating the skill assessment so it measures judgment rather than trivia also needs psychometric or instructional-design input.
