AWS Practice Exam Review: Score Higher Without Burning Out
Quick answer: Take one practice exam, then review it fully before taking another. Review in 25 to 45 minute blocks and sort every miss or guess into four buckets: didn't know it, misread it, rushed, or guessed right. Study only the patterns that repeat.↗ Share on X
To review AWS practice exams without burning out, stop taking full exams back to back. Take one practice exam, then spend at least as much time reviewing it as you spent taking it. Review in short blocks of about 25 to 45 minutes, sort every missed question into one of four buckets (didn't know it, misread it, ran out of time, guessed right), and only study the weak topics that show up more than once. Most people get tired because they retake exams to see a higher score, not because they study too much. Better review means fewer exams and less stress.
The rest of this article gives you a review system you can use for the AWS Cloud Practitioner, Solutions Architect Associate, or any other AWS exam.
Why do AWS practice exams wear you out so fast?

AWS and PMP at the Same Time: A 16-Week Dual Study Plan →AWS exams are long. The associate-level exams usually have 65 questions and give you over two hours. Many questions are long stories about a company with a problem, followed by four answers that all sound possible.
That pattern drains your brain for a few reasons:
- Every question is a reading test. You have to find the one detail that matters, like "lowest cost" or "least operational overhead."
- Wrong answers look right. AWS writes answers that are technically possible but not the *best* choice.
- Scores feel personal. A 62% can feel like failure, so people rush into another exam to fix the feeling.
- Reviewing feels slow. Reading 30 explanations is boring, so people skip it and take another exam instead.
The last two points are the trap. Taking exam after exam teaches you to recognize questions you've already seen. Your score goes up, but your understanding may not.

How many practice exams should you take?
There is no magic number, but quality beats quantity. A simple guide:
| Stage | What to do | Goal |
|---|---|---|
| Early (first weeks of study) | 1 practice exam as a baseline | Find out what you don't know |
| Middle | 1 exam per week, fully reviewed | Fix weak areas |
| Final 1 to 2 weeks | 2 to 3 fresh exams you've never seen | Check readiness |
| Exam week | No full exams the last day or two | Rest |
The rule that matters most: never take a new exam until you've finished reviewing the last one.

How to Use Cloud Labs to Ace Behavioral Interviews →After each exam, put every question you missed, plus any you guessed on, into one of four buckets. This shows you why you're losing points.
Bucket 1: Didn't know it
You had no idea what the service does or how it works.
Fix: Study the topic. Read the AWS documentation page or your course video on that service.
Bucket 2: Misread it
You knew the material but missed a keyword like "most cost-effective," "highly available," or "with the least changes."
Fix: Practice reading. Before choosing an answer, underline (in your head or on paper) the requirement words in the question.
Bucket 3: Ran out of time or rushed
You knew it but picked fast because the clock was running.
Fix: Practice pacing, not content. On a 130-minute exam with 65 questions, you have about 2 minutes per question. Flag hard ones and come back.
Bucket 4: Guessed right
You got it correct, but you weren't sure why.
Fix: Treat it like a wrong answer. A lucky guess on test day won't repeat.
Keep a simple spreadsheet or notebook with four columns: question topic, bucket, AWS service, one-line lesson. After two or three exams, patterns jump out. You might find that half your mistakes are Bucket 2, which means you don't need more videos. You need to slow down and read.
How do you review one exam step by step?
Here's a review session you can actually finish without frying your brain.
1. Take a break first. Wait at least an hour after the exam, or do the review the next day. Reviewing while tired leads to skimming.
2. Set a timer for 25 to 45 minutes. Review questions until the timer ends, then take a 5 to 10 minute break away from the screen.
3. Start with wrong answers. For each one, read the question again before reading the explanation. Try to find the right answer yourself.
4. Read why each wrong option is wrong. This is where most learning happens. AWS often reuses the same wrong-answer patterns.
5. Write one short lesson. Example: "S3 Glacier Deep Archive = cheapest storage, but retrieval takes hours." Keep it to one line.
6. Sort it into a bucket. Add it to your tracker.
7. Move on to guessed questions. Same process.
8. Stop after two or three blocks. If you're not done, finish tomorrow. A 65-question exam might take two or three review sessions, and that's normal.
Which AWS topics usually need the most review?
The exact focus depends on which exam you're taking, so always check the official exam guide on the AWS Certification website. It lists the domains and how much each one counts. That said, these areas trip up many learners because the services sound alike:
- Storage classes: S3 Standard, S3 Infrequent Access, Glacier tiers, and when to use EBS vs. EFS.
- Databases: RDS vs. Aurora vs. DynamoDB, and when you need read replicas vs. Multi-AZ.
- Networking: VPCs, subnets, security groups vs. network ACLs, and NAT gateways.
- Decoupling: SQS vs. SNS vs. EventBridge.
- Security and identity: IAM roles vs. users vs. policies, and AWS KMS for encryption.
- Cost questions: Reserved Instances vs. Savings Plans vs. Spot Instances.
When two services keep getting mixed up, make a two-column comparison card. Write each service at the top and three differences underneath. Ten good comparison cards can be worth more than another full practice exam.
How do you keep your brain from burning out?
Burnout during cert prep usually comes from long sessions, no breaks, and studying while stressed about the score. These habits help:
- Cap your daily study. For most people with a job, 60 to 90 focused minutes a day is easier to sustain than a 5-hour Saturday.
- Separate test days and review days. Don't take an exam and review it in the same sitting.
- Mix in light study. On tired days, flip through your comparison cards for 15 minutes instead of skipping entirely.
- Track progress by bucket, not just score. Seeing "Bucket 1 mistakes went from 18 to 7" feels better and tells you more than a percentage.
- Sleep before exam day. Cramming the night before often hurts more than it helps.
- Take a full day off each week. Your brain needs it to lock in what you studied.
What score should you aim for on practice exams?
AWS exams are scored on a scale from 100 to 1,000. The passing score depends on the exam (for example, 700 for Cloud Practitioner and 720 for the associate exams), but this is a scaled score, so it doesn't convert directly to a percentage.
Different practice exam providers make their questions harder or easier than the real test, so a percentage from one provider doesn't mean the same thing as a percentage from another. A practical approach:
- Aim for steady scores in the mid-70s to 80s on exams you haven't seen before.
- Look for a trend across two or three fresh exams, not one lucky high score.
- Make sure your Bucket 1 list is getting shorter.
If you've memorized a question bank, your score on that bank doesn't count. Only fresh questions tell you the truth.
What should you do after your next practice exam?
Before your next exam, set up your tracker: a sheet with four columns labeled topic, bucket, service, and lesson. Then take one practice exam and don't take another until you've finished reviewing it, in 25 to 45 minute blocks over one to three days. When you're done, count your mistakes in each bucket. If Bucket 1 is largest, schedule study time for those services. If Bucket 2 is largest, practice reading questions slowly for a week before buying any new course or exam bank.
FAQ
How many AWS practice exams should I take?
Quality matters more than quantity. Take one as a baseline, about one per week fully reviewed, and two or three fresh exams in the final week or two. Never start a new one before reviewing the last.
What practice exam score means I'm ready for AWS?
Look for steady scores in the mid-70s to 80s on fresh questions you haven't seen before, across two or three exams. Scores on a question bank you've memorized don't count.
How long should I study each day for an AWS certification?
For most working people, 60 to 90 focused minutes a day is easier to sustain than long weekend sessions. Take a full day off each week.
