A nested multiple choice question includes a stem (the lead-in description) and four statements in ascending roman numeral order; i.e., i, ii, iii, and iv. The four answer options (a, b, c, and d) then include various combinations of those statements as being correct; e.g., (a) i and ii are correct; (b) ii and iv are correct, and so forth. OREA is phasing out this type of question, but some are apparently still in the exam database and can pop up, particularly on the first two pre-registration courses. (Note: The vast majority of questions are standard four option MCQs, but it never hurts to be prepared). Passit includes a 10-page discussion (plus detailed examples) of nested MCQs in the study guides for Real Estate as a Professional Career and Land Structures and Real Estate Trading.
