Is the Unified State Exam (USE) a good or bad thing?

Thank you for the explanation; it seems we live in parallel worlds... let's say I have many colleagues and acquaintances from this country.

Truth is multifaceted. I also have enough acquaintances who live permanently in the USA and those who lived (and attended school) there for several years

Does the USA not have free education?

And what is the percentage of government-funded spots there?

Do you really think that this country lives off its parents?

For a while, everyone lives off their parents. But America itself lives off other countries.

What is included in the concept of "expensive"?

I will express only my own opinion: I call education expensive when it is not accessible to practically anyone who wishes and is capable of learning.
