You've done the right thing. Andrew Brown's free CLF-C02 course on freeCodeCamp is genuinely one of the best resources out there for the AWS Certified Cloud Practitioner exam — 14 hours of solid, hands-on content that actually explains how AWS works, not just what to memorize.
So you watched it. Maybe you took notes. Maybe you followed along in the console.
Now what?
The gap nobody talks about
Here's the thing about video courses — even great ones. They're built for the average student, not for you.
You don't have equal gaps across all four CLF-C02 domains. Nobody does. Most people who've worked in tech already have a mental model of cloud concepts and global infrastructure. Where they actually bleed points is Cloud Economics, Billing, or the Shared Responsibility Model — topics that sound simple but hide a lot of tricky nuance in exam questions.
The problem is that a 14-hour course can't know that about you. It covers everything at the same pace. You're watching the billing section at 1.5x speed because you think you've got it — and that's exactly the section that shows up on your exam as three questions you're not quite sure about.
Finishing the course is not the same as knowing where you stand.
What the CLF-C02 actually tests
The exam is 65 questions across four domains:
- Cloud Concepts — 24% of the exam
- Security and Compliance — 30%
- Cloud Technology and Services — 34%
- Billing, Pricing, and Support — 12%
Most people study in proportion to the content in the course. The exam tests in proportion to the domains above.
Security and Compliance is the largest domain, and it's also the one most people underestimate because the concepts feel familiar — IAM, shared responsibility, encryption. But the questions are scenario-based. They don't ask you to define the shared responsibility model. They give you a situation and ask you who is responsible for what, and why, and the wrong answers are very plausible.
If you don't know which of these domains is soft for you specifically, you're guessing at your study plan.
The move most people skip
Before you buy a practice exam, before you re-read your notes, before you schedule anything — take 10 questions.
Not to pass. Not to score. Just to see where the gaps actually are.
This is what ExamCoach does. You start a free Daily Quiz on CLF-C02, answer 10 adaptive questions, get an instant explanation for every answer, and immediately see which topics are pulling your score down. The Weak Area Tracker shows you domain-by-domain where you're strong and where you're not — colour-coded, with trends over time as you keep practicing.
It's not another course. There are no videos. No modules to complete. You show up, answer questions on your actual weak spots, read the explanations, and leave knowing more than when you started. Five to ten minutes. Every day until your exam.
Why this works for CLF-C02 specifically
The CLF-C02 is an exam where concept knowledge matters less than applied reasoning. You can understand what EC2 is and still get a question wrong about which EC2 pricing model is most cost-effective for a specific workload described in three sentences.
That kind of question only reveals your gaps when you get it wrong and read why. No video teaches you that. Adaptive practice does.
The other thing that makes ExamCoach useful at this stage: it generates questions from the weakest areas of your performance, not from a static question bank in a fixed order. So if you're repeatedly shaky on Cost Explorer vs Budgets vs Pricing Calculator, it keeps drilling that cluster until the pattern clicks.
A simple plan for the next two weeks
If you've finished the free course and your exam is in two to four weeks, here's what the last stretch looks like:
Days 1–3: Take a Daily Quiz each day. Don't grind. Just see what comes up and where you're uncertain. Let the Weak Area Tracker build a picture.
Days 4–10: Use Drill Mode on your two or three weakest topics. Fifteen minutes a day is enough. Read every explanation, even on questions you got right — the reasoning matters more than the answer.
Days 11–13: Take a full-length practice exam (ExamPro's practice exam is good for this). Use the results to confirm which areas improved and which still need work.
Day 14: Light review only. Look at your weak area trends. Trust the work you put in.
