A different order
We don't start with the definition. We start with the value.
Traditional learning goes word → meaning → example. We flip it: show the upgrade first, so you feel why the word matters before you ever learn what it means.
See the mistake
Start from the vague word you already overuse — big, good, reduce — and feel the ceiling it puts on your band.
Climb the matrix
Watch one idea rise from Band 6 to Band 9 — same meaning, sharper collocation, more natural English.
Weigh it like an examiner
Every lesson closes by measuring the word against the examiner's criteria — naturalness, register and lexical resource — then you use it yourself.
