Your first language can influence English, but it does not define you.
Slavic and Eastern European languages are diverse. A Polish speaker, Ukrainian speaker and Bulgarian speaker may bring very different grammar, pronunciation and communication habits into English. Age, region, education, profession, other languages and individual experience also matter.
TEO Academy uses possible cross-language patterns as a starting point for assessment, never as a fixed label. Your tutor listens to your real communication and focuses only on the areas affecting your clarity, confidence or goals.
