Preparing for an AWS certification exam requires focus, strategy, and a clear understanding of best practices. As a AWS certification mentor and someone who’s been through these exams myself, I’ve seen (and experienced) the common mistakes that can throw even well-prepared candidates off course. But, as Yoda wisely said, “The greatest teacher, failure is.” By learning from these missteps—you can approach your AWS exam with confidence, avoid potential pitfalls, and make the most of your preparation.

I’ve been known to let my inner geek out at public talks and events… I hope I’ve managed to somewhat strike a balance with only some nods and a few quotes on this article compared to other engagement I’ve done at DTX Europe (see cover image).

This guide is tailored for AWS learners at all levels, from those starting out to seasoned professionals aiming for advanced certifications. Here are 10 proven strategies to help you stay focused, manage your time, and prepare you for exam day.

Start with the Exam Guide—Including the Appendix 📖

Overlooking the exam guide is a classic misstep. AWS provides a comprehensive breakdown of topics, weighting, and structure, with an appendix listing services that could appear on the exam. Focus on this list; newer services take time to be added to exams, so use it as a checklist. If you can’t confidently explain differences between services in the same category, go back and study them. “Informed, you must be,” and the exam guide is your roadmap.

Plan Your Time Per Question ⏲️

Time management is key to a successful exam experience. Calculate your time per question based on the exam’s length and question count. For instance, the AWS Solutions Architect Associate exam gives you 130 minutes for 65 questions, allowing about two minutes per question without factoring in review time. By planning ahead, you ensure you can “stay on target” and avoid last-minute rushing.

Use the Flag Option Wisely ⛳️

If you hit a challenging question, flag it and move on. Spending too long on one question can throw off your timing and build frustration. Often, returning to flagged questions later helps provide clarity or lets you view it from a fresh perspective. In my experience, using the flag option strategically helps maintain momentum, preventing any single question from derailing your focus.

Avoid the Trap of Second-Guessing 🤔

Second-guessing can derail even the most prepared exam-takers. Everyone is different, but for me through my own experience, I’ve learned that while reviewing flagged questions can be beneficial, re-checking every answer often creates unnecessary doubt. I limit my review to flagged questions as I tend to overthink. Trust in your initial response—“Your focus determines your reality.”

Practice Exams: Timing and Familiarity ⭐️

Timed practice exams are crucial. They reveal areas that need improvement and help you get comfortable with pacing. In my own experience and in working with others, I’ve found that practice exams build both confidence and focus. Treat them as training; they’re less about scoring perfectly and more about building stamina and familiarity with the format.

Get in the Exam Mindset with a Pre-Exam Mock 💪🏽

On exam day, doing a quick practice test can help get you in the right mindset. Don’t stress over your score—use it as a warm-up to ease into the exam’s style and reduce nerves. This pre-exam mock helps sharpen focus and feels like a reliable warm-up. “Do or do not. There is no try.”

Review Knowledge Gaps with Targeted Practice 🎯

After studying a domain, reinforce it with domain-specific practice questions. This targeted approach strengthens understanding before moving on to the next topic. From personal experience, I’ve seen how focused practice on weaker areas helps build a solid foundation, making it easier to tackle the broader scope of questions on exam day. “Patience you must have.”

Don’t Overthink It—Go for the Simplest Solution 🏁

AWS exams often test for the most practical, cost-effective solution. When faced with complex questions, resist the urge to overthink. I’ve learned that focusing on clear, straightforward solutions is usually the best approach. “Keep your concentration here and now” and avoid unnecessary complexity—AWS rewards practical, effective solutions.

Trust Context Clues and Keywords🕵🏻‍♀️

AWS exam questions frequently contain keywords or clues that guide you toward the right answer. Words like high availability, scalable, or cost-effective can hint at the solution. Training yourself to recognize these clues helps streamline your reasoning and saves valuable time. “Your eyes can deceive you; don’t trust them”—focus on the words that matter.

Don’t Be a Rescheduler—Go for It! 🙈

Rescheduling is tempting, but if you are mocking well in practice exams, go for it! I’ve seen this in myself and others, waiting for the perfect moment rarely leads to progress. I’ve taken and cleared over a dozen technical exams in the past 4 years (only 2 AWS ones so far) and I can tell you I never felt ready, but I always was. Trust your preparation and go for it. Each exam is a learning opportunity.

Commit to Continuous Learning and Growth 📚

AWS exams are challenging, but they’re manageable with the right strategies. Each test offers an opportunity to deepen your understanding and refine your approach. By applying these tips, you’ll approach your exam with greater confidence, avoid common mistakes, and continue developing skills that will serve you throughout your cloud journey. Embrace each step and remember, “Your focus determines your reality”—stay steady, and you’ll find success on the path to AWS mastery.
