A senior tutor at Bristol University has admitted that the university is finding it difficult to police hi-tech cheating in student exams. Bristol's senior physics tutor, Jeff Odell, has conceded that "of course students cheat" and the only solution is to ensure the deterrent of "dire consequences" for those who are caught. The admission came following a Bristol undergraduate's claims that the university has failed to implement its policy on cheating with graphical calculators, which can store data used to cheat in exams. Bristol generally allows the use of the calculators in exams, but it has a policy to wipe their memory before an exam begins and bans the use of calculators above a specified memory size.
