Calculator models NOT included in either of these lists will be permitted to be used for APhO examinations only if they satisfy the following criteria:

  • Calculators should not have a graphing mode.
  • Their display must not have more than three rows for any function, like matrix mode.
  • Calculators should not contain equation solver or integration function.
  • Should not have stored physical constants (e.g. gravitational constant) in their inbuilt memory.

Such calculators must be presented for verification to the centre coordinator half an hour prior to the examination on the day of examination and the decision of the Centre Coordinator to allow/disallow a particular calculator will be final and binding.
