The tutorial system at Oxford and Cambridge is fundamental to methods of teaching at those universities, but it is by no means particular to them; Heythrop College (University of London), for instance, also offers a tutorial system with one-on-one teaching. It is rare for newer universities in the UK to have the resources to offer individual tuition ; a class of six to eight (or even more) students is a far more common tutorial size. At Cambridge, a tutorial is known as a supervision.
