During examinations offered by the School of Nursing, all calculators used by students must be non-programmable and non-communicating. Calculators acceptable for use during quizzes, tests and examinations are intended to support the basic calculating functions required. For this purpose, the use of the Casio 991 series calculator is permitted and is the only approved calculator for Arts and Science students. This calculator sells for around $25 at the Queen's Campus Bookstore, Staples and other popular suppliers of school and office supplies.
