Printed book or digital PDF?
Choose a paperback printed and delivered by Lulu, or a PDF to download through Gumroad and print yourself. Books are sold individually. Lulu confirms shipping costs and delivery estimates before payment. Check the book language and level before ordering.
What is included?
Each book contains a complete story, six missions, hints and explained answers. Its pack page lists the available formats and page count. All books in the current collection are in French.
Is a teacher pack included?
Yes. Each Academy PDF purchase includes three separate PDF files alongside the illustrated book: story and reading texts without the questions; illustrated questions and activities with space for answers; and worked answers and the teacher guide, including hints and PER curriculum references. These files are in French and accompany individual Academy PDF purchases. They are not included with printed books or Travel, Knowledge or Language.
Does it cover a whole school year?
No. The French-speaking Swiss Academy books practise selected PER curriculum skills at the level stated on each page. They support learning rather than replace a complete school programme. Travel focuses on cultural discovery.
Can I use it in class?
One licence covers a household OR one named educator with their own pupils. Additional educators need their own licence. Redistribution and resale are not permitted.
How are the books made?
Generative AI tools were used for parts of the writing and illustration process. The illustrated editions include AI-generated artwork. Previews show actual pages.
