Model predictions and data for study-time investment and percentage passed are shown together with the average amount of study time per passed exam. NR = exam in no-resit condition, UR1 and UR2 = the first and resit exam in unconditional resit condition, UR1&UR2 denotes overall results for the unconditional resit condition, meaning the results for both R1 and for UR2 on trials in which UR1 was failed. Same terminology applies for GR = grade restricted resit condition, and PR = probability restricted resit condition. M = mean, SD = standard deviation.
