Read the first domain right now, free.
The Getting Started domain is open to everyone. Thirteen lessons that take you from what AWS is to exactly how the exam is scored and booked. No account, no card, nothing to install.
- What AWS actually is, in plain language
- What a certification proves, and how employers verify it
- The full AWS certification portfolio, tier by tier
- Role-based pathways for architects, developers, security and AI
- Exactly how CLF-C02 is structured, timed and scored
- What it costs, how to register, and what exam day is like
A score is not a study plan
Most practice tools stop exactly where the useful work begins.
A percentage tells you what happened. Passing gets easier when the next screen tells you why it happened and what to do next.

AttemptDiagnosisFocused studyProof
The product in motion
Watch one attempt become a focused pass plan.
Timing, topic coverage, and repeated mistakes converge into one clear recommendation, so the next study session starts with a purpose.

Confidence waits until the signal agrees.
A recent full mock, stable first-look accuracy, pacing, and coverage must point in the same direction.
Your shortest path to pass-ready
Stop wondering what to study next.
The app closes the loop between practice and progress, so each session starts with evidence and ends with proof.

Lesson 2 of 6
Choose between Amazon SQS and Amazon SNS
Turn a recurring confusion pair into one clear decision: queue work for consumers, or fan a message out to subscribers.
Exam tip
If the scenario needs decoupling and each message processed once, think queue. If many endpoints need the same event, think pub/sub.
Key takeaway
SQS stores messages for polling consumers. SNS pushes a published message to multiple subscribers.

Built for the decision after the score
Do more than answer questions. Know what the answer changes.
The difference is not a bigger question counter. It is a tighter feedback loop between every attempt and the next useful action.
| Study moment | Score-only report | Connected feedback loop |
|---|---|---|
| After a mock | A percentage and an answer key | Domain gaps, pacing signals, and confusion pairs |
| Next study session | Pick another random question set | Open the lesson or drill with the highest point upside |
| After a retake | A higher score that may include answer recall | First-look accuracy stays visible beside repeat performance |
| Before exam day | Hope that practice scores transfer | Validate timing, coverage, and a fresh full-mock signal |
| Access | Depends on the provider and plan | The complete study system for $0 |
One attempt should improve more than your score.It should improve your next decision.
Turn my first mock into a plan A signal, not a vanity score
Know what is strong - and what is only familiar.
Retakes help you learn, but remembered answers should not manufacture confidence. Readiness stays grounded in fresh performance, domain coverage, pacing, and the mistakes that keep repeating.

A complete system, not a pile of tools
Every feature has one job: move you closer to pass-ready.
Learn, practice, review, and measure in one connected workflow. Your mistakes keep their context, and your next action never starts from zero.
- Reduce test-day friction
Make test day feel familiar
Practice 20, 35, or 65-question sessions with the timer, flagging, multi-select rules, option elimination, and review pressure already built in.
- Trust the signal
Know if the score is real
First-look accuracy, rushed mistakes, confusion pairs, and domain coverage separate genuine readiness from answers you simply remember.
- Raise the weakest domain
Study the highest-impact gap
Blueprint-mapped lessons, exam traps, and key takeaways turn a weak domain into a specific next session.
- Beat distractor answers
Stop mixing up AWS services
Comparison-first service cards show what each service does, when to choose it, and the look-alike answer it is designed to beat.
- Refresh in minutes
Review without reopening a course
Domain summaries, comparison tables, and exam wording patterns keep the exact refresher one tap from every mistake.
- Close repeat gaps
Turn every miss into a win
Wrong answers carry explanations, notes, and targeted re-drills so the same gap cannot quietly survive into exam day.
- Protect study time
Spend time where points live
Short focused sets target weak domains and topics instead of burning study time on material you already own.
- Study anywhere
Use every spare study window
Responsive lessons, service references, and review flows stay fast on phone, tablet, and desktop so short sessions still move the score.
The official blueprint stays visible
Put study time where the exam puts its weight.
Every lesson, drill, and mock stays connected to the four CLF-C02 domains, so the easiest topic cannot quietly steal time from the most valuable one.

Questions before you commit
The honest answers.
No inflated promises. No artificial urgency. Just a focused system for making your CLF-C02 preparation measurable.
Start with a free baselineIs this an official AWS product?
No. CLF-C02 Exam Prep is an independent study tool and is not affiliated with or endorsed by Amazon Web Services. The domain structure follows the published CLF-C02 exam guide.
Is the complete app really free?
Yes. The lessons, practice exams, mock builder, analytics, wrong-answer review, cheat sheets, service references, and progress sync are available with a free account. No credit card is required.
Can I use it if I am completely new to AWS?
Yes. Start with a baseline if you want an immediate diagnosis, or begin with the blueprint-mapped lessons and service cards before taking a timed mock.
How closely does practice match the real exam experience?
The full mock uses 65 questions, a 90-minute timer, the published domain weighting, multi-select rules, flagging, answer elimination, and a review palette designed to make the exam workflow familiar.
Does a readiness score guarantee that I will pass?
No honest prep tool can guarantee an exam result. The readiness signal is decision support: it combines fresh performance, first-look accuracy, domain coverage, pacing, and repeat weak areas so you can judge risk with better evidence.
Can I study on my phone?
Yes. The responsive web app is designed for phone, tablet, and desktop study, so lessons, mocks, explanations, and review sessions stay usable in short study windows.
