Four Weeks of German Evenings

A Zurich investment coach adds a four-week German course to a full-time job and passes B1 without turning language into her career.

Charlene Cong runs a personal finance channel. Its own description calls it Switzerland's most-followed English-speaking personal finance and investment show. She is an investment coach based in Zurich, a former JPMorgan investor, and most of her content is about portfolios and early retirement. The German video is an exception. She made it after she sat the German B1 exam.

The title lists the facts: she passed German B1, starting from A1, in six months, with a full-time job. She moved from Hong Kong to Switzerland in 2022 and worked for the first two years. German was not her job; she learned it after the move while her career continued in English, in finance.

The chapters are "My journey", "Intensive course", "Self-created pressure", "Obsession", and "Tools I used". She promises three tips and some free tools, and she names three tools: the Slow German podcast on Spotify, Preply, and a sheet of notes on OneDrive. The transcript gives one concrete figure for the course: two hours a day, Monday to Friday, for four weeks, ten hours a week on top of a full-time job, forty classroom hours in total. She calls the course a game changer. The video does not say what changed, only the hours. It also does not give the school's name, the homework load, or the details of the oral exam, and it does not say how many Preply lessons she took.

One chapter is titled "Self-created pressure". She does not name a specific Swiss certificate or office; the chapter is about pressure she applied to herself. The four-week course sits inside the six months from A1 to B1, not in place of them. After class she still wrote her own notes. The title includes the full-time job, and the timeline in the description supports it: work first, then a concentrated push in the months before the exam.

She says she passed B1.
