But to intentionally disadvantage a minority group is to discriminate against that minority group.
Are you suggesting that intentionally disadvantaging a group is not discriminating against that group?
Or are you suggesting that unintentionally disadvantaging a group is not only not discriminating against that group, but that also it is is also excusable and needs no correction? i.e. that the consistent, albeit unintentional, disadvantaging shall continue?

With respect to entrance examinations specifically - while I have zero experience of context with the situation today, I fully appreciate how entrance examinations can be intentionally and unintentionally exclusionary - and yet still be seen as innocuous. A good example is in the (historical) [entrance exams for the UK's Grammar School systems which are sat at age 11[(https://en.wikipedia.org/wiki/Eleven-plus#Controversy); while the grammar-school system was ostensibly universal and open to all, the entrance exams with questions predicated on a familiarity with middle-class culture naturally disadvantaged working-class students.
