Beyond the lessons
Assess, practise, pass the proof
Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.
Assess yourself
12 quizzes
At the end of the lessons: passed at 70%, they confirm the skill.
Practice
3 guided labs
Proof
1 practical proof
A practical proof is a challenge, a capstone or a declared lab.
Used by the mission “Bring a broken server back”, which has its proof.
