What does it mean when it says "pass or fail is determined before you even take the A-Level exam"?
I'm a foreigner, and I'm just interested in the British examination system; I don't intend to take any exams. However, there's a concept I can't understand no matter how many times I read about it.
I found a website explaining the British examination system in my native language, and it says, "University admission is determined (conditionally) before you actually take the A-Level exam."
I can't understand what it means for admission to be determined before taking the exam!
This sentence was written using a translation machine, so the meaning might not come across...
I've never taken university entrance exams in my home country, so I'm not confident this information is accurate, but in my home country, if there are three students—A who scored 70%, B who scored 60%, and C who scored 50%—and there are two spots available, then A and B would pass, and C would fail. That's the kind of exam I understand.
That's the only image I have, so the explanation that "admission is determined (conditionally) before taking the exam" doesn't make sense to me.
How can admission be determined before taking the exam?
