Why GrammarMetric

Three things most schools get wrong.
We built around them.

🎯

You start at your real level

A free placement scan plus a teacher's confirmation puts you in the right class on day one, anywhere from Foundation through Band 8+. No wasted months in a class that's too easy or too hard.

🗣️

Small enough that you speak

Paired and small-group formats mean every student produces English in every lesson. IELTS rewards what you can say and write, not attendance.

🕹️

Practice you'll actually do

Homework here is a game we built ourselves: your unit's vocabulary, drilled with spaced repetition inside a real browser game. Your progress reports back to class.

The pathway

One pathway. Four stages.
Join at yours.

Every stage is available as small-group, paired, or individual lessons. The placement scan below tells you where to start.

Foundation

Pre-A2 to A2

The 500 words and core patterns everything else is built on, with guided speaking from lesson one.

Intermediate

B1 · IELTS 4.5 to 5.5

Break the plateau: collocations, opinion language, and the jump from understanding English to using it.

Upper-Intermediate

B2 · IELTS 5.5 to 6.5

Academic vocabulary, precision, and exam technique. This is university-gate territory.

Advanced

C1+ · IELTS 7.0 to 8+

Band 7 and beyond: task response, hedging language, and retrieval speed under exam pressure.

Who it's for

Two reasons students come to us.
Both get a real method.

Nearly everyone who studies here arrives for one of two reasons. The honest part: the work looks similar either way, because a good band and genuinely good English come from the same place.

🎯

“I have a test to take.”

You're sitting IELTS soon, usually within the next 12 weeks to a year, for university admission, a visa, or work. We work backward from your target band and your test date, with focused practice across all four skills, real exam technique, and honest progress checks, so test day holds no surprises.

📈

“I just want better English.”

You're not chasing a certificate. You want to genuinely improve your listening, reading, writing, and speaking. IELTS is simply the most efficient way there: it forces balanced progress across every skill instead of letting your strong ones cover for your weak ones. Many of these students sit the test in the end anyway, once they see how close they are.

📚 Cambridge English materials

Taught from Cambridge, not homemade photocopies.

We teach from Cambridge's published course books, the same internationally benchmarked series used in accredited programs worldwide, then drill the gaps between lessons with the games we build in-house.
