How learning is structured

A clear path from your first word to fluency

Every learner follows the same simple, predictable structure — so you always know where you are and what comes next.

Step 1 Language

Step 2 Level

Step 3 Step 4

Unit Lesson

Inside every Unit

A unit groups a series of lessons and always finishes with a Review Lesson — which comes with a video.

L1 Lesson 1 4 learning pillars

L2 Lesson 2 4 learning pillars

L3 Lesson 3 4 learning pillars

L4 Lesson 4 4 learning pillars

VIDEO R Review Lesson Quizzes + video-based quiz on the unit

Some units include 3 or 5 lessons — but the Review Lesson always comes at the end.

Modular template

Inside every Lesson

A universal 7-component framework — courses can switch any pillar on or off, so the same template powers General English, Business English, Kids English and future tracks.

Vocabulary

Core words and phrases with meaning, examples and practice.

Grammar

Clear rules shown in plain language with simple examples.

Function

The communicative purpose — how to greet, request, agree, decline.

Pronunciation

Real-World Practice

Grammar & Function

Rules shown in context so usage feels natural.

Reading & Listening

Multimedia content with comprehension checks for both skills.

Questions & answers

Everything you need to know

What does my subscription include?

One subscription unlocks every level in your language category — A1 through C1 — including all units, lessons, quizzes and review lessons. You can choose a monthly or yearly plan.

Which devices can I learn on?

Kustau is designed mobile-first and works on phones, tablets and desktop. Your progress syncs across every device, so you can switch seamlessly.

How do lessons and units work?

Every lesson is built around the same four pillars: vocabulary, grammar & function, reading & listening, and sounds & pronunciation. A unit then groups a series of lessons (typically four) and always finishes with a Review Lesson — which includes a video-based quiz on the previous lessons in the unit.

Am I eligible for a certificate?

To receive the final certificate of completion, you'll need to pass every Review Lesson in your level. Review Lessons can be retaken as many times as you need.

How is my progress tracked?

Your dashboard shows clear progress bars for every level, unit and lesson, plus your recently completed lessons and upcoming reviews — so you always know your next step.

How do payments work?

Subscriptions are billed securely through WooCommerce Subscriptions, with Flutterwave supporting recurring payments — including Mobile Money options such as Orange Money and MTN MoMo.
