One thing the Tories may try to do is deregulate student fees, so universities can charge what they want. An index of what that could mean is Harvard University, in the USA.
The total 2015-2016 cost of attending Harvard College without financial aid is $45,278 for tuition and $60,659 for tuition, room, board and fees combined.
$45,278 is £29,400. Per year.
