Bulgarian grammar has a reputation for a reason. People hear that it’s complicated and decide the language is impossible before they’ve written a single sentence. The reputation is not entirely undeserved as some of it really takes time. But most of what feels overwhelming at first is a small set of patterns that keep repeating.
The problem is that reading about a pattern and being able to use it are two different things. These exercises are repetitive by design: you see the same structure in different sentences until your brain stops treating it as a rule to remember and starts treating it as something that just sounds right.
