CloudRank is a skill-tracking algorithm that is directly affected by the results of quiz sessions you undertake in Test Mode.
You can find your CloudRank in your dashboard
Your CloudRank changes with each question you attempt, allowing our system to adjust the skill level of subsequent questions and guide you from topic to topic. We use adaptive learning technology with more than 8000 questions - each followed by comprehensive explanations - to test your skills on every cloud platform AND to help you through any weak spots. Our adaptive learning technology means that every answer changes both your CloudRank and the difficulty level of subsequent questions.
