Guessing is risky — it adds uncertainty to the student’s score.
However, guessing can easily be justified if it improves a student’s expected score, as is the case for a student who can safely eliminate one or more answer choices as wrong prior to randomly guessing (i.e., the return justifies the risk).
The student improves his expected score by improving his or her odds (by eliminating wrong answers). Even the College Board acknowledges this ‘smart guessing’ in their SAT exam instructions.
Why not guess even smarter, by improving the student’s odds even further, by utilizing all the relevant information available at the time the guess is made?
