Multiple choice or objective response is a form of an objective assessment in which respondents are asked to select only correct answers from the choices offered as a list. The multiple choice format is most frequently used in educational testing, in market research, and in elections, when a person chooses between multiple candidates, parties, or policies.
Victoria M for Amexwrite mentioned the cons of of Multiple Choice Questions, "Lack of partial credit: Even when students have some knowledge on a question, there is no credit for their knowledge if they pick the wrong answer. Free response questions allow takers to demonstrate their understanding of the subject and get partial credit.
Ambiguity:Any failure to interpret the information the intention by the test setter may result to an incorrect response even when the taker had a valid response. The term "multiple guesses" is the right term for describing this scenario. Another form of test allows takers the freedom to make their argument from their point of view and there is potential to receive some credit.
Logical reasoning: Test takers can rule out the answers due to infeasibility or test each answer individually especially for math. It increases their chances of getting the right answer even when they do not understand the subject matter. Examiners include some answers simply for this reason such providing the equation."
