Berufsbezogenes Deutsch — two dozen chapters from working life: onboarding and teamwork, giving instructions, reporting and explaining, handling conflict, professional writing, job applications, customers and orders, workplace safety, negotiating and presenting, meetings, phone and video calls, project work, trade fairs, professions and workplaces, the workshop floor, and employment law — IT and tech German (standup, code review, incidents, data quality, lakehouse, cloud, dashboards, architecture) now lives in its own IT track. Each chapter with reading, listening, writing, speaking, 25 graded dialogues, vocabulary, grammar and an LLM-graded final test. Aligned with Goethe- and Telc-Beruf exam preparation. Chapters are in German; everything around them is in English.
