Abstract
Ninety undergraduate introductory psychology students predicted their numerical scores on a multiple-choice final exam directly before the exam was passed out (pretest prediction) and just after completing the exam (posttest prediction). Based on their all-but-final-exam point totals, students were ranked with respect to class standing and categorized as above average (top third), average (middle third), or below average (bottom third). Below average students significantly overestimated their final exam scores on both pretest (9.47%) and posttest (7.73%) predictions. Average students significantly. Overestimated their scores on pretest (5.33%) but not posttest (2.13%) predictions. Above average students, however, were fairly accurate for both types of prediction, slightly but not significantly underestimating (about 2%) their exam scores.
