Mnemonics, Teach Back and the Vault

Three tools for the material that won't stick on its own.

Mnemonics

Your exam comes with a deck of memory devices for its most confusable material — each with an illustration, shown right in the guide sections where they apply. The mnemonics page has two modes: study (browse the deck) and test (type the device and its mappings from memory; graded leniently — it's a study aid, not a score). Want one that doesn't exist? Ask Miles to devise a mnemonic for any topic in your guide, and save the good ones to your deck.

Teach Back

The strongest test of understanding is explaining something in your own words. Pick a concept, explain it (type or dictate), and Miles grades the explanation against the study guide — what you nailed, what you fuzzed, what you missed, with citations. The feedback is for you alone: Teach Back scores never touch your readiness or your flashcard schedule.

The Vault

Every question you miss — and every question you revealed the answer to — lands in your Vault, and stays there until you clear it out. It's your personal weak-spot bank.

• Drill it. One tap starts a session over exactly your vaulted questions.
• Answer one correctly and it's marked mastered — but it stays listed until you remove it, because one right answer isn't the same as knowing it.
• Remove a question yourself once you're confident it's dead.

An empty Vault in your final week is one of the best readiness signals there is.
