Changing answers[edit]
The theory that a student should trust their first instinct and stay with their initial answer on a multiple choice test is a myth. Researchers have found that although people often believe that changing answers is bad, it generally results in a higher test score. The data across twenty separate studies indicate that the percentage of "right to wrong" changes is 20.2%, whereas the percentage of "wrong to right" changes is 57.8%, nearly triple.[13] Changing from "right to wrong" may be more painful and memorable (Von Restorff effect), but it is probably a good idea to change an answer after additional reflection indicates that a better choice could be made.
