Why pre-made decks work — and where they stop
For the memorization layer of a course — lab values, ion charges, cranial nerves, vocabulary — a good pre-made deck saves you the hours of card-building that stand between you and actually studying. These decks cover exactly that layer: the canonical facts that show up on the exam no matter which professor you have.
What they can't cover is your own class — the specific emphasis of your lectures, the notes you took, the chapter your professor cares about. That's the other half: Cram builds decks from your own material with AI and schedules every card with spaced repetition so it's still there on exam day.
