&gt; somewhat controversial secondary education system<p>{{citation}}<p>I&#x27;m a german, have gone through gymnasium and have a sibling who didn&#x27;t, and many other family members who went through either of the three tracks. I have never heard anyone complain and am not aware of any controversy whatsoever, especially since students are provided ample opportunity to switch tracks at multiple points, and upgrade after the fact.<p>Please provide reference to this controversy you claim.
