Why Active Recall Beats Re-Watching Cantrill Videos
AWS courses are great content delivery — but watching a 30-hour course twice doesn't make you fast at scenario MCQs. Active recall — pulling the right AWS service out of memory in response to a scenario — is exactly what the exam tests.
Cramberry pairs active recall with spaced repetition: the algorithm that controls when you next see each service detail, IAM permission, or networking concept. Services you keep missing come back tomorrow; the ones you've nailed wait two weeks. Your study time goes to the exam-guide domains where you'd actually miss points.
Dunlosky et al. (2013) found practice testing and distributed practice deliver the highest learning utility across academic subjects — the same engines drive AWS cert prep.
