Calculators

[NOTE: changed for 2025/26 academic year to ensure consistency with university exam invigilation guidance.]

Scientific, but not graphical or programmable, calculators are allowed in PX*** coded examinations. If your calculator cost less than £20 then it is probably allowed, if it cost more than £50 then it is probably not (see below for further guidance). If you normally use a calculator which would be in breach of these rules then you must obtain one that will satisfy them. It is in your own interests to practice with the calculator you will use in examinations prior to your first examination!

The Mathematics Department says: the use of any mathematical software and sophisticated calculators is permitted, indeed encouraged where appropriate, in Mathematics lectures, coursework and homework, even if for credit. HOWEVER, calculators are NOT permitted in any MA*** coded examination.
