Costs that differ enormously by place

Two courses with identical fees can differ by a great deal a year on everything else. Accommodation is the largest lever and varies hugely between cities, and between institution-owned and private. Transport is the second — a place you can walk across costs nothing to move around.

So compare cities rather than institutions on this axis, and ask the specific question: what do students on this course actually pay for accommodation, and how far out do they live in order to pay it? The published estimate is an average, and averages hide exactly the thing you need.
