The path to mastery

Every learner steps onto the mat at white belt. Each rank maps to a real proficiency level, so you always know exactly how far you've come — and what comes next.

  1. White belt

    A1 · Beginner

    Build the foundations — articles, basic tenses, and word order.

  2. Yellow belt

    A2 · Elementary

    Past and future forms, comparatives, and everyday connectors.

  3. Green belt

    B1 · Intermediate

    Perfect tenses, conditionals, and reported speech with confidence.

  4. Blue belt

    B2 · Upper-intermediate

    The passive, relative clauses, and nuanced modal verbs.

  5. Brown belt

    C1 · Advanced

    Inversion, cleft sentences, and sophisticated discourse markers.

  6. Black belt

    C2 · Mastery

    Grammar becomes instinct. You write and speak with native precision.

道 · The Way

How we train

Mastery isn't memorising rules — it's repetition until grammar becomes instinct. Every part of the Dojo is built around deliberate practice.

A clear path

A structured curriculum from A1 to C2. No guesswork about what to study next — just follow the path.

Daily katas

Short, focused drills that build muscle memory for grammar. Five minutes a day beats five hours once a month.

Instant feedback

Know why an answer is right or wrong the moment you submit, with clear explanations from our senseis.

Visible progress

Watch your belt rank climb as your skills grow. Streaks and milestones keep the momentum going.

Crafted by senseis

Every lesson is written and reviewed by expert English teachers — not generated and forgotten.

Train anywhere

Practise on any device, online or off. Your dojo travels with you — commute, café, or couch.
