For many years there has been
a continuing discussion about
the ideal number of choices in a
multiple- choice question (MCQ).
The debate has been centred on
being able to ask more questions in
a given time with a small number
of options and reducing the impact
of guessing with a larger number of
options. This paper describes a trial
of three- , four- , and fi ve- choice
MCQ papers, and the impact on
medical and pharmacy students.
