Twenty-two years of ARWU data, mapped year by year. The US has shed a third of its top-100 seats since 2003. China went from zero universities to twenty-two. A single French university merger jumped fifty places in a decade. The ranking behind this series' shortlist has never been still.

Article 3 flagged China as unresolved – cheap, fast-climbing, and largely absent from international shortlists. This piece goes inside a system that's genuinely unfamiliar from the outside: how admission works for international applicants, what the top-tier universities actually teach, and the gap between China's research output and its visibility to the families deciding where to apply.

US sticker prices eliminated the US from this series' shortlist on cost alone. But sticker price and actual price are not the same number. What need-blind admission and full-need financial aid actually require – the profile, the paperwork, the thresholds – to bring the real cost at a top-tier US university close to zero.
