Short audio drills for the errors that survive years of fluency. Two minutes a day, on the patterns natives never correct you on — because they understood you anyway.
A sentence plays with one word muted. You fill the silence in your head — then it plays again, revealed. This is for / since, the leak almost every Slavic speaker carries into B2.
You don't have a vocabulary problem. You have a handful of patterns that fossilised 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.
The patterns that mark intermediate-but-imperfect speakers: present perfect with for/since, articles, common phrasal verbs. Drill them until you can't get them wrong.
The patterns that hold back fluent speakers: phrasal-verb particles, conditionals, dependent prepositions, register in spoken English. The mid-career polish nobody at work corrects.
Collocation, idiom, subtle register shifts. Where errors stop being grammatical and become lexical-stylistic. For the long-plateau speaker tired of "good enough."
Native apps for iOS and Android — designed for screen-off listening on the commute, with lock-screen controls. Drill while you walk; review at your desk.
