You can’t use Duolingo alone.

I find it works better for languages with simple grammar rules Swedish/Danish/Norwegian

I was able to jump from Duolingo straight to young adult books, and became conversational from there.

Languages with complicated grammar rules, you don’t get the support you need for the grammar foundation and is only really helpful for learning vocabulary, not necessarily how to form sentences.

You need to have multiple sources of learning, not just relying on Duolingo
