Ch. 02 The path

A path through everything you must know.

Every exam gets a Space. Upload your materials and Deckio maps the actual topics inside them into an ordered path, the way a good tutor would plan your month. Practice moves the needle; mastery is measured per topic, and readiness is tracked to the day of the exam.

  • Topics extracted from your content, not a generic syllabus
  • Weak spots resurface in the drill queue automatically
  • One glance tells you whether you are ready

Ch. 03 Echo

A coach in the corner of every page.

Echo is the quiet orb that travels with you through Deckio. It sees which cards you hesitate on, explains what is shaky in plain words, and quizzes you before the exam gets the chance.

You’ve answered Again on the Krebs-cycle cards twice today. Want the 60-second version before they come back around?

Explain it like I’m exhausted. It’s 11pm.

Echo

Deal. The cycle is a merry-go-round that strips electrons off acetyl-CoA and hands them to NAD+ and FAD. Eight steps, two CO2, one ATP per turn. The electrons pay for everything later.

Ch. 04 Memory

Reviews land the moment before you forget.

Deckio runs SM-2 spaced repetition, the algorithm behind two decades of Anki lore. Miss a card and it returns tomorrow. Nail it and the interval stretches: one day, three, seven, sixteen.
