Based on the review, I would rate the "Menschen A2.1 Arbeitsbuch" 4 out of 5 stars. It is a solid workbook that effectively supports learners at level A2.1, but may benefit from additional audio materials and more varied exercise types.
Academic institutions sometimes provide public access to these solutions for their students, which can be found on sites like IS MUNI . menschen a2 1 arbeitsbuch answers
