The AWS Certified Cloud Practitioner (CLF-C02) is the most popular entry-level cloud certification in the world. The good news: you don't need to spend a dime to pass it.
We've curated every worthwhile free resource into a single guide, organized by how you should use them.
Free Courses
AWS Skill Builder (Official)
AWS offers a free Cloud Practitioner Essentials course on Skill Builder. It covers all four exam domains in about six hours. This should be your starting point — it's made by the same people who write the exam.
freeCodeCamp YouTube Course
Andrew Brown's 14-hour CLF-C02 course on freeCodeCamp's YouTube channel is the most comprehensive free video course available. It goes deeper than you strictly need for the exam, which is actually a good thing — the extra context makes the concepts stick.
Free Practice Questions
BrainyBee CLF-C02 Hive
We maintain a free bank of 500+ AI-generated CLF-C02 practice questions on BrainyBee. Every question includes a detailed explanation and maps to a specific exam domain. You can build custom practice tests, filter by domain, and track your score over time.
AWS Official Practice Questions
AWS provides a free set of 20 official sample questions. These are helpful for understanding the question style, but 20 questions aren't enough to study with — treat them as a format preview.
Free Study Guides & Cheat Sheets
AWS Whitepapers (Required Reading)
The CLF-C02 exam guide specifically references these whitepapers. Read at least the first two:
- Overview of Amazon Web Services — the single most important document for CLF-C02
- AWS Well-Architected Framework — understand the five pillars at a high level
- How AWS Pricing Works — pricing questions appear throughout the exam
BrainyBee AI-Generated Study Notes
BrainyBee's hive system auto-generates cram sheets and key-term glossaries from the exam content. These aren't a substitute for the whitepapers, but they're excellent for review in the final week before your exam.

Tips From People Who Passed
Based on feedback from BrainyBee users who passed CLF-C02:
- Don't overthink it. This is a foundational exam. You need breadth, not depth. Know what each service does, not how to configure it.
- Memorize the Shared Responsibility Model. At least 5-10 questions will test this concept directly or indirectly.
- Understand billing and pricing. Know the difference between On-Demand, Reserved, Spot, and Savings Plans. Know what AWS Organizations and Consolidated Billing do.
- Take at least three full practice exams. If you're passing them consistently, you're ready.
Free vs. Paid: Is It Enough?
Yes. Every resource in this guide is genuinely free — no trials, no credit cards, no "freemium" bait-and-switch. The CLF-C02 is the one AWS certification where free resources are more than sufficient. Save your money for the exam voucher.
