Learn German: German Grammar Complete: Workbook: Exercises for All Levels from A1 to C2 (A2, B1, B2, C1) for Beginners and Advanced Learners: 300+ ... German Learning & Self-Study (Deutsch Lernen)

This is a workbook that delivers on its promise of comprehensive German grammar practice, with its 300+ exercises covering everything from basics to advanced concepts, and with practical sentences that can help with real-world speaking. I appreciated the answer key for self-checking and the logical progression through difficulty levels, it seemed to be a nice complement. Not exactly exciting (it's grammar after all), but relevant enough if you’re serious about working on your language skills. If you're serious about mastering German grammar beyond tourist phrases, this workbook is a good bet.

This is a very good book that allows someone to be able to learn the art of the German language. It is written with precision and is simple to understand as well. It is full of workbook exercises as well which can help someone with further understanding and being able to practice learning the language too. I highly recommend.
