Being native doesn't matter. Plenty of people here learned English by classes, tv and online while not being a native English speaker and you wouldn't even notice it ( eg. me)

Some are noticable, like people from the netherlands have a certain accent while speaking and you still understand them perfectly.

Here's my point again: A native speaker has no single advantage over a non-native speaker, if they are at a certain level.

> compulsory classes don't get you anywhere near native proficiency.

It gets you good enough to explain yourself and speaking. You don't need native proficiency.

What you need is to practise it afterwards, if multiple years go by. Even native dutch speakers that went abroad don't speak dutch anymore well by lack of repetition over ( a lot of) years.

PS. My original reply was not on a question. But on the statement quoted above.
