Because they want to say that China is bad. When, as you say, US is the outlier in inventing strange ways to admit kids to college. I'm from Brazil and the entrance is exam is similar to China, there is a single exam and the note is used to determine which college you can go.
I don’t really find it strange, if anything a slavish obsession to test scores strikes me as strange. School is just an artificial institution like any other, it’s not as if getting good grades is equivalent real-world success or “true” intelligence.
The US also has the best universities in the world, by and large, (even if the regular education system is lacking), so I am pretty skeptical of the idea that raw test scores as the sole criterion would lead to better outcomes.
Raw test scores are a good idea in many countries because it reduces scope for corruption + gives even the poorest kids a chance. Though I would argue there needs to be multiple chances a year and not just 1.
Wow! So advanced! Does the rest of the world do the same with jobs (a single exam to determine if you get hired to any company), or does it invent strange ways to interview and hire applicants well?
