CKAD Exam Tips
Study the official exam blueprint — weight percentages tell you exactly where to invest prep time.
Practise scenario-based questions regularly — every modern cert exam is scenario-heavy.
Use spaced repetition to retain what you've learned (JT Exams does this automatically).
Book your exam date once you're scoring 80%+ consistently on practice tests.
Review explanations for every wrong answer, not just the question — the 'why' is what makes it stick.
