Hey there @Emmytender,
Happy New Year to you too! And thank you for your question to the community.
I've had a **** at the official test website and there are a few links with download options for preparation material: https://***.telc.net/pruefungsteilnehmende/sprachpruefungen/pruefungen/detail/deutsch-test-fuer-zuwanderer-a2-b1.html#t=2
Here is an Übungstest: https://***.telc.net/fileadmin/user_upload/deutsch-test-fuer-zuwanderer_uebungstest_1_1_.pdf
They also advertise this Übungsheft here for 10€: https://***.telc.net/shop/detail/article/deutsch-test-fuer-zuwanderer-a2-b1-uebungsheft.html?p=245
Or have a **** at this one: https://de.pons.***/produkte/pons-deutsch-test-fuer-zuwanderer-978-3-12-562714-7?gclid=Cj0KCQiAsdHhBRCwARIsAAhRhskRIUIjhFxoqozd8Rqc4vGdPN5vc3ZOL7TNq7ycrwLrYZOCfXEBCVEaAk58EALw_wcB
Maybe some other members have more information on materials that helped :-)
All the best,
Isa
