Looking for a resource on declinations. I am now using Duolingo and hoped I was wrong. Unfortunately, I still struggle with the same things, so my theory "Duolingo is great as futher exercise source or as the first sample of German learning, but nothing more" seems to hold. I think I have seen workbooks on declinations but cannot remember names, I'll try to google the stuff. However, would anyone remember or does anyone have a good recommendation, please? I need tons of exercises and examples. I more or less understand the issue, I get the real basics, I get quite a lot of things right, but I still make tons of mistakes and it's a shame and it is one of the things standing between me and progress.
I've used Schaum's Outline of German Grammar and German Grammar Drills to varying degrees to drill German inflectional endings specifically. The workbook Hammer's Practising German Grammar is similar to the previous two but is meant to accompany the reference manual Hammer's German Grammar and Usage. Almost every exercise in Hammer's workbook links to an explanation in the reference book right down to explicit mention of the subsection number.
You can also practice the case endings indirectly by using Practice Makes Perfect German Pronouns and Prepositions and Practice Makes Perfect German Sentence Builder since learning to use prepositions and/or constructing sentences correctly can often mean you have to get the declension right.
Any of these books (especially an edition excepting the most recent one) can be found for pocket change on Amazon Marketplace and similar but be careful about buying used copies of workbooks since these can already be marked up by previous owners. Since you're in Europe, it'd probably be better to order through Amazon UK Marketplace or similar to reduce the chances of being charged a lot for shipping and customs.
You could even use FSI German Basic Course to practice handling the case endings. Look especially at the substitution and conversion/transformation drills instead of the variation, vocabulary and translation drills since the latter three wouldn't be ideal for simple drilling based on one cue or pattern. Look through the grammar notes of both books and do the drills for topics for which you want extra practice. Obviously you could do these drills by writing down your answers rather than saying them aloud as intended.
