How do you use a palace to study exam material?

Turn each fact into an image, place them in order at loci, and grade yourself by re-walking the route.

For lists, sequences, and structured facts (the cranial nerves, the causes of a war, a legal test's elements), a palace excels: encode each item, place it, review the walk. It's strongest for material that is discrete and ordered. It's not a substitute for understanding — a palace helps you retain and retrieve facts you've understood, but memorising a formula you can't apply just gives you a parrotable image, not comprehension.
