It is well known at the university which I went to (Cambridge), that way more money is spent on each student than the home-tier tutition fee (it is partly payed for by the exorbitant cost of international fees, and the student loans of home students are payed by the taxpayer).
UK-wide, how much money is spent on average on university students?
This question was inspired by some of the answers to this question: Why are online lecture notes usually not accessible to non-students?
