Practice retrieval (i.e. testing) has been shown to be one of the most potent methods of learning. Impactful learning takes place when individuals practice testing within a simulated examination setting. The ‘testing effect’ is a proven phenomenon that occurs as individuals progress over time resulting in high scoring. TrueLearn leverages the ‘testing effect’ to reinforce important principles while developing improved problem-solving skills necessary to optimize performance on ABEM examinations.
