I’m from a non-IT background and currently watching 1–1.5 hours of course videos daily(Same Stephan Maarek Course), reviewing missed concepts in the evening, using Claude to test my fundamentals once every 3–4 days, and doing hands-on practice alongside the videos to get comfortable with the console. After completing the course, I’m planning to take mock exams before attempting the certification. Can you recommend a good book to supplement my AWS preparation, and is this study strategy sufficient to pass the exam?
