I said this here before, but this is exactly what is going all over the world whenever "affirmative actions" are used.

The only difference is that in this specific case, they decided to use a clear different required test score in order to apply the unfair advantage at selection.

In most other places, specifically in the US they use soft, improvable information (such as an "essay") to cover their base and make it non-obvious that the selection process is unfair. The most famous case would be the Asian discrimination case at Harvard, weirdly everyone is mostly ok with that one
