How I'm Studying for AWS Cloud Practitioner: A System, Not Just a Course
No "how I passed" here. My exam is six weeks away. This is the study system I'm using for AWS Cloud Practitioner: flashcards, a why-I-missed-it log, and an AI tutor that won't give me the answer.
My AWS Certified Cloud Practitioner (CLF-C02) exam is booked for November 2026, in English, which isn't my first language. I haven't passed yet, so this isn't a "how I passed" post. It's the system I'm using to get there, written down while I'm using it, so you can copy what works or tell me what doesn't.
TL;DR* Study by exam weight: Domains 2 and 3 are 64% of the exam.
- Turn every concept into spaced-repetition flashcards, written in my own words.
- Keep a practice log of why I missed each question, not just a score.
- Learn the story behind each rule (a real breach, a real lab). It's what makes it stick.
- Be careful with braindump sites.
1. Start from the exam guide, not the course
The official CLF-C02 exam guide tells you exactly where the points are:
| Domain | Weight |
|---|---|
| 1. Cloud Concepts | 24% |
| 2. Security and Compliance | 30% |
| 3. Cloud Technology and Services | 34% |
| 4. Billing, Pricing, and Support | 12% |
Security plus Technology and Services is 64% of the exam. I keep this table as a checklist and only tick a domain off when I feel solid on it, not when I finish the videos about it.
My main course is the Cloud Practitioner learning path on AWS Skill Builder. The exam guide decides what I prioritize; the course is how I cover it.
2. One note per topic, with flashcards inside
I study in Obsidian, a free Markdown note-taking app. Each topic gets its own note (IAM, S3, Shared Responsibility Model, Global Infrastructure...), and each note links to the domain it belongs to.
The flashcards live inside the notes, using the Spaced Repetition plugin. One line per card, with question and answer separated by

What's the difference between scalability and elasticity?::Scalability is the ability
to grow to handle more load; elasticity is scaling automatically up AND down to match
demand, so you don't pay for idle capacity.
For RDS vs. EC2, who patches the OS?::RDS: AWS does (managed service).
EC2: you do (EC2 only virtualizes the hardware; you own the OS).The plugin schedules reviews, so cards I know well show up less often and the ones I miss come back sooner. The important rule: write the answers yourself. Copying a definition from a slide feels like studying, but it isn't.
3. A practice log that tracks why, not just the score
A score of 72% tells me almost nothing. So for every missed practice question I log:
1
2
3

### YYYY-MM-DD — Domain X (topic)
- Question gist: ...
- My answer: ... — Correct / Incorrect
- Why I missed it / what to review: ...
- Flashcard added? yes/no
- Still unclear? -> add to my questions listAfter a few sessions, the "why" column shows patterns. Maybe I keep mixing up two services, or I misread "MOST cost-effective". Patterns are what I fix, not individual questions.
4. Learn the story behind the rule
The topic that finally made Domain 2 click was a real incident, not a definition. I asked a simple question: does an EC2 instance that runs 24/7 need permanent AWS keys? Following that question led me to IAM roles, the Instance Metadata Service, SSRF, the 2019 Capital One breach, and IMDSv2. I wrote it up here .
After that, least privilege and shared responsibility stopped being vocabulary. I can explain both with a real example of what goes wrong without them.
I do the same with hands-on labs. CCP is a conceptual exam, but building a small EC2 instance with Terraform (post here ) made Regions, AMIs, security groups, and storage concrete in a way slides didn't.
5. Ask a person, every week
I have a weekly sync with an AWS partner, and I keep a running list of questions for it. Some are exam doubts, but the most useful ones are things the material can't answer:
- In real projects, how do you choose between ECS and EKS, or RDS and Aurora, when the exam makes them sound interchangeable?
- What's the most common architecture mistake you see beginners make?
- Which domain do people underestimate the most?
Writing questions down as they come up means the meeting is never "uh, I think I'm fine?". If you don't have a mentor, an AWS community or a study group works the same way.
6. An AI tutor that doesn't give me the answer
I also use an AI assistant (Claude) as a tutor, with a written set of rules for how it should teach me:
- Don't give the answer right away. Ask what I think first and give a hint.
- Explain the mechanism, the why, not just the steps.
- Connect new concepts to what I already know. I'm stronger on the dev side, so it uses programming analogies for infrastructure topics.
- End with a check question I have to answer in my own words.
That last rule is the most valuable. An AI that explains things very well can easily become passive reading. Making it ask me keeps it active recall.
7. Studying in English, on purpose
The exam is in English, so I switched my whole study environment to English: notes, flashcards, even my conversations with the AI tutor. Translating in my head during the exam costs time I won't have. I also keep a small list of my recurring English mistakes, separate from the cloud content.
If you're a non-native speaker, check AWS's "ESL +30" accommodation, which gives 30 extra minutes. It's best to request it before you book the exam.
8. A warning about braindump sites
Some popular "practice question" sites are reported to contain real, leaked exam questions. Studying from them can violate the AWS Certification Agreement you accept when you register. It also teaches you to memorize question-and-answer pairs, which doesn't help when the real exam rewords the question.
What I do instead: use AWS's official practice questions on Skill Builder and reputable practice exams for most of my testing. When I do look at other questions, I read the explanation to understand why an answer is right, and then write my own flashcard.
Where I am now
All four domains have starter flashcard notes, the practice log is ready, and the exam is about six weeks away. I'll post an honest update afterward, whether I pass or not.
Over to you: what's the one study habit that made the biggest difference for your first AWS certification? And if you've already taken CLF-C02, which domain surprised you the most?
