How this course works
A 60-second tour of every part of the tool — the path, a lesson, the bonus rounds, quizzes, the exam, and your certificate. No prior experience needed.
Each lesson explains one idea in plain language, with a tip for the common gotcha.
Type real markdown, watch the live preview, then check your answer for XP.
Finish a lesson to open the next one. Twelve in total, then the final exam.
When a task asks for Snacks, type it with the capital S. The checker treats uppercase and lowercase as different — snacks and Snacks are not the same. Match the words exactly as written.
Anatomy of a lesson
Peek at an example- Eggs
Stuck? Take a peek
Every lesson has a Peek at an example button. It shows the same idea using different words, so you learn the pattern without just copying the answer. Use it as often as you like — no penalty.
Bonus round & quick check
Totally optional. Want a challenge and extra XP? Open the bonus, solve a slightly trickier version, and claim your reward. Skip it anytime — it never blocks your progress.
A one-question quiz to lock in what you learned. Answer it correctly to finish the lesson, earn a badge, and unlock the next step. Pick the wrong one? Just try again.
Your score, at a glance
How many tasks you've nailed in a row. Keep it alive!
Points from tasks, bonuses, and quizzes. They only go up.
Every 100 XP bumps your level. The bar shows your way there.
Tip: the 
icon mutes or unmutes the sound effects. Your progress saves automatically.
After all twelve lessons, write one short post that uses every trick. A checklist lights up green as you go — turn it all green and graduate (with confetti).
Pass the exam, add your name, and open a printable certificate. Save it as a PDF to share or print for the fridge.
