You're already fluent. You lead meetings, you're understood, you get by fine. But a few patterns still slip out when you speak — and because people understand you anyway, nobody corrects them. That's why they stay.
You don't have a vocabulary problem. You have a handful of patterns that locked in years ago and now run on autopilot — "since two years," "discuss about it," "I'm working here since Monday."
We isolate them one at a time and drill them by ear, the way you actually use English: out loud, in the moment, under a little pressure. No grammar lectures — just the sound of getting it right until wrong feels wrong. Built for your phone: screen-off on the commute, lock-screen controls, one earbud at the gym.
No streaks. No owls. No guilt.
✗ "I'm working here since Monday."→✓ "I've been working here since Monday."
