Could you build this?

Partial The practice app, answer explanations, and mistake review are buildable with vibe coding. Licensed or legally sourced past-paper content and original listening audio are the hard requirements.

What it would actually take: The app needs a question bank with answer explanations, a spaced-review engine, and a frequency analysis of vocabulary and grammar across papers. The critical inputs are the past papers and their audio, which need licensing or manual creation by Japanese-language educators. Native-speaker recording and pedagogical review are required.
