What’s the difference between a 7/10 vs 8/10 school? The rating is given by some rating agency, based on nothing but test scores. See my post on “methodology”

The state-level ranking is equally unreliable.

A 8/10 school here will pale against an average Singapore school in terms of standardized benchmark. So why treat it like Princeton?

A typical Singapore school may be rated 9/10 on many aspects not only academics.
