A few helpful answers.
What do I receive?
CAUMIO packs are digital learning materials. Each product listing states the exact files, page counts, level and explanation language included. No physical product is shipped.
Which explanation language should I choose?
Choose the language you find easiest to understand. The target language is German. Each edition is purchased separately; one pack does not include every explanation language.
How do I use the files?
Unzip the download on a computer. Open the PDFs in a PDF reader and the HTML activities in a modern browser. Printing is optional. Device and browser support may affect interactive features.
Are these an official course or exam certificate?
CAUMIO packs are independent self-study resources. They do not include teacher support, official exam registration or certification, and do not guarantee an exam result.
