Grammatik aktiv

There are lots of Cousin es here, but Grammatik aktiv is pretty solid.

Maybe try Grammatik Aktiv (book). It has exercises by levels and it’s sorted by topics

Grammatik Aktiv

Once you get into grammar, I would suggest two books called „Grammatik Aktiv“. Incredibly useful exercises.

Also I would recommend Grammatik Aktiv and A-Grammatik for self-study. Second this: Grammatik Aktiv is quite fun actually.

I personally have "Grammatik aktiv" and love it - perfect for self-study (at least for me).

I am also doing Grammatik aktiv (both parts), so I feel that even though I am aiming for the telc B2, all the provided resources are still solid.

That's the book I am already using... So I'm in the right direction I would say.

I found Grammatik Aktiv extremely helpful
