Minutes after studying something using a strategy of passive review, students perform better than they would if they had practiced retrieval.3 The feeling that you’re learning more when you’re reading rather than trying to recall with a closed book isn’t inaccurate. The problem comes after. Test again days later, and retrieval practice beats passive review by a mile. What helped in the immediate time after studying turns out not to create the long-term memory needed for actual learning to take place.
Yeah mate, and most exams are not designed to test long term retrieval. That's why your idiot MIT project worked. If you'd had months between classes you'd have been fucked
