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, offers a tutorial system but with one-on-one teaching. Another example is Imperial College London, where tutorials in groups of 3 take place.[2] It is rare for newer universities in the UK to have the resources to offer individual tuition; a class of six to eight students is a far more common tutorial size. At Cambridge, a tutorial is known as a supervision.
