You will need a scientific calculator for examinations. It should have trigonometric functions (with degrees and radians), roots and powers, exponents, logarithms, factorials, combinations and permutations. A fraction key is also useful. You do not need a graphical calculator. Some people borrow calculators for exams. This is not a good idea because you will not be familiar with it and you shouldn't waste time in exams learning how to work your calculator.

The college examination regulations state that:

'The unauthorised use of material stored in a pre-programmable memory will constitute academic misconduct. You are advised to use a calculator without this facility.'

If you have a programmable calculator you must clear the memory before entering the exam room.
