Premium
The platform is free for everyone — every teaching course, always. Premium is for proving what you've learned: practice courses, official exams, and a verifiable certificate.
Learning is free.
Premium is how you prove it.
All teaching courses are free — every lesson, every lab, the AI coach, for anyone. Practice courses and exams are premium: that's where you test yourself, sit an official exam, and earn a Certificate of Completion with a unique ID anyone can verify. Selected live Zoom classes are included too.

What membership adds
On top of everything that's already free to everyone:
Companion practice for what you've learned: a timer, one-shot answering, and a per-module scorecard that shows exactly what to study again.
Apply for an official exam, sit it in one timed sitting, and earn a Certificate of Completion.
Didn't pass? Re-apply and sit it again. We want you certified, not caught out.
Objective questions are graded on the spot; written and spoken answers are scored by an on-device AI, marked generously to your level.
Every certificate carries a unique ID that anyone — an employer, a school — can check on our public verification page.
The English coach and speech models run privately in your browser. Your writing and your voice are never uploaded.
Some online Zoom classes are included in membership — we'll say so when a class is a member benefit.
The occasional members-only course, alongside the free teaching track that stays open to everyone.
What's free, what's premium
All the teaching is free, forever. Premium covers practice, exams and certification — we never paywall knowledge.

Questions
Yes — and it stays that way. Every teaching course, lab, and the AI coach are open to everyone, no account needed. Premium doesn't take anything away.
Testing and proving what you've learned: practice courses with scorecards, official exams, and a verifiable certificate. The teaching is free; the certification is the membership.
It runs for a set period — you'll see the exact from and until dates on your account page, along with the days remaining.
Practice and exams lock again — but any certificate you've already earned is yours forever, and stays publicly verifiable.
Some are. Zoom classes are registered per class, and selected ones are included as a member benefit — we'll say so on the class.
Get in touch and we'll talk it through — we keep it affordable for the community, and we consider sponsored places.
