At this time of year we often receive enquiries about the use of calculators in exams, either at the desk or on Asklive.
John Arnold provided this info for Law Library staff but I thought worth sharing Library wide.

Summary:
Calculators are not permitted unless the examiner has authorised their use and must be self-powered, without data storage facilities, noiseless and handheld. It is your responsibility to provide a suitable calculator and to have it checked prior to reporting for the exam/test should the examiner require it. The examiner will advise you if you need to have your calculator checked.
Calculator Checks (PDF, 27KB) shows a list of examinations where Standard Non-programmeable Calculators have been authorised for use. All students sitting for these examinations must have their calculators pre-approved before arriving at the exam room.
Calculator checks for tests/exams requiring this will take place in Law 436 each Wednesday from 12.45 – 1.15.
