Preregistered semester-long classroom experiment (230 undergraduates): multiple-choice retrieval with corrective feedback beat restudy of the same questions three weeks after the last practice session (80.15% vs 70.07%, dz = 0.58); no benefit for related, non-practised questions (62.42% vs 62.32%, BF10 = 0.074). Notes were allowed during practice and test. Full text read.
