Reading, quizzes, exercises — what each module does

Every trail mixes three module types. Here’s what to expect from each one.

A Yoonle trail is a sequence of modules. There are three types, and the AI mixes them to keep you engaged and to actually verify you’ve learned something.

Reading — short, focused passages

These are the workhorses. A reading module is a few hundred words, structured with headings, examples, and where useful, code blocks or diagrams.

They’re designed to be readable in 2–7 minutes. No filler, no SEO fluff, no "in conclusion" paragraphs. Just the content.

  • Earn XP: no — reading modules track progress only.
  • Why no XP? To prevent gaming — a 50-module reading-only trail would otherwise be a free XP farm.
  • Can you skip? No. The next module unlocks when you mark this one complete.

Quizzes — verify you understood

Quizzes are short multiple-choice or true/false checks placed after key reading modules. Usually 3–5 questions.

They’re not a final exam — they’re an active-recall step that turns passive reading into something that sticks.

  • Earn XP: yes — typically 20 to 60 XP depending on difficulty and length.
  • Retakes: no in V1. Pick carefully — the module is graded on your first attempt.
  • Failure: doesn’t block the trail. You can keep going, but you don’t earn the XP.

Exercises — apply it hands-on

Exercises ask you to do something with what you just learned. Sometimes it’s a coding challenge, sometimes it’s a writing prompt, sometimes it’s "go cook this and tell us how it went".

Exercises are evaluated by an AI grader against a rubric the trail creator agent defined when generating the trail.

  • Earn XP: yes — typically 30 to 150 XP. The longer/harder the exercise, the more XP.
  • Submission: type or paste your answer; the grader returns a score and feedback.
  • Retakes: no in V1.

Why the order matters

The AI sequences modules so each one builds on the last. A quiz never tests something you haven’t read yet. An exercise never asks you to apply something you haven’t practiced. This is why we lock progression — it’s how the trail stays coherent.
