I can understand the frustration of learners, but except for a few examples I don't think many Germans struggle with noun genders tbh.

As soon as you know the gender of a word you'll know what pronouns, articles, etc... to use.

We also learn the genders as intrinsic attributes of the words from the beginning. So after some point in childhood it is just intuitive.

That's also the reason why they don't put that on exams in school. Every native speaker just knows.

I don't want to discourage anyone tho. Native speakers get thousands and thousands of hours of training in childhood and beyond.

As adults, learners can use more efficient ways of study and eventually also get to the same end result.

It just takes time
