Prepa teaches your exam's full syllabus, drills you on the topics you keep getting wrong, and puts you in a real cloud console to build things yourself — then tells you when you're ready to book.
30 practice questions, two lessons, a lab and a mock exam — free. 20 certifications, or bring your own notes.
Which AWS service provides a fully managed NoSQL database with single-digit millisecond latency at any scale?
DynamoDB is AWS's managed NoSQL store, built for consistent single-digit-millisecond reads at any scale. RDS and Aurora are relational; Redshift is built for analytics, not low-latency lookups.
↗ docs.aws.amazon.comAWS, Azure, Google Cloud, CompTIA, Cisco and CISSP — or describe any other exam and Prepa builds the syllabus for it.
Every multiple-choice answer is confirmed by a second AI before it reaches you. If the two disagree, you never see the question.
Nothing comes from a stale dump. Every session is written for your exam and the topics you keep getting wrong.
30 practice questions, two lessons, a hands-on lab and a mock exam — free, and no card to sign up.
There's no question bank to purchase and no course to hunt down. Prepa builds the syllabus, the lessons, the labs and the questions around the exam you're actually sitting.
Pick one of 20 certifications, describe any other exam, or upload your own study notes. About thirty seconds later you have a full syllabus, weighted exactly like the real test.
Lessons teach the topic properly — decision tables, examiner traps, the facts worth memorising. Then a hands-on lab drops you into a real cloud console to do it for yourself.
Every session brings fresh questions aimed at the domains dragging your score down, with explanations you can check and a tutor for the follow-up questions.
Sit timed, full-length mocks in the real question formats. Your readiness score and per-domain mastery tell you when you're ready — and the daily plan gets you there by your exam date.
Your exam's full syllabus, weighted exactly like the real test, taught with decision tables, the traps examiners love, and the facts worth memorising — then a knowledge check that proves it stuck.
Fresh exam-style questions every session, aimed at your weakest domains. The more you practise, the more the questions target what's actually holding your score down.
Guided labs you run in your own free-tier cloud account — build the VPC, deploy the pipeline. Checkpoints confirm you did it, and a cleanup list means nothing keeps running and nothing gets billed.
Timed, full-length mocks in your exam's actual question formats — multiple choice, drag-to-order, matching, Yes/No grids, even typed CLI commands. No surprises on the day.
One number that climbs as you improve, backed by mastery tracking in every exam domain. Book with evidence instead of a gut feeling.
Set your exam date and Prepa builds the daily plan — weighted to your weak areas, rebalanced when life gets in the way, and honest with you about pace.
Every question and lesson has a tutor attached. Ask a follow-up, ask for a mnemonic, ask for it again but simpler — until it actually makes sense.
Questions you miss and key facts from your lessons turn into flashcards automatically, scheduled to reappear right before you'd have forgotten them.
A second, independent AI answers every multiple-choice question with the answer key hidden. If it disagrees, the question is thrown out before it ever reaches you.
Explanations link to the official documentation — AWS, Microsoft Learn, Google Cloud, Cisco. Links anywhere else, or links that have gone dead, are stripped before you see them.
Nothing hurts your score like revising a wrong answer for a week. Three checks stand between a new question and your screen — and any one of them will throw it out.
Questions follow your exam's published domains and weightings — the vendor's own outline, not somebody's guess at what might come up.
A different AI answers the question with the answer key hidden from it. If the two don't agree, the question is thrown out. You only ever see the ones they both got right.
Every explanation cites the vendor's own documentation, and we test the link works before you see it. Made-up URLs get stripped out.
Still think a question is wrong? Flag it. We re-check it independently, and if the check agrees with you it comes straight out of your review queue.
Domains and weightings come straight from each vendor's published outline, so you spend the most time where the exam puts the most marks. Sitting something that isn't listed? Describe it, or upload your notes, and Prepa builds the syllabus anyway.
A question bank sells you someone else's answers, frozen the day they were written. Here's what you get instead.

| Answers you just have to take on faith | Every multiple-choice answer confirmed by a second AI |
| No source to check when you disagree | Every explanation links to the vendor's own documentation |
| The same questions, memorised by round three | Fresh questions every session, aimed at your weak spots |
| Written for an exam version that's since changed | Generated against the current published blueprint |
| Theory you read but never actually do | Guided labs you build in your own cloud account |
| Booking the exam and hoping for the best | A readiness score and mastery in every exam domain |
| A PDF chained to your desktop | Installs on your phone and works offline |

Every multiple-choice question is answered a second time by a separate, independent model that never sees the answer key — it sits the question cold. If its answer doesn't match, the question is discarded and you never see it. Explanations link to the vendor's own documentation, and those links are checked before delivery. If a question still looks wrong, flag it: it gets independently re-checked and removed from your review queue if the check agrees with you.
Prepa ships 20 certifications built from their official exam blueprints — including AWS Certified Solutions Architect – Associate, AWS Certified Cloud Practitioner, AWS Certified AI Practitioner, AWS Certified Developer – Associate, AWS Certified CloudOps Engineer – Associate, AWS Certified Data Engineer – Associate and more — and works with any other certification exam you describe. You can also upload your own PDF study notes and Prepa will build questions from them.

Question banks recycle a fixed set of questions and ask you to trust the answer key. Prepa checks its own work — every multiple-choice key is blind-verified by a second, independent model, and every explanation cites the vendor's own documentation. On top of that you get lessons that teach the syllabus, questions tuned to your weak areas, hands-on labs in the real cloud console, spaced-repetition flashcards, and a readiness score that tells you when you're prepared.
Labs are guided, step-by-step exercises you run in your own free-tier AWS, Azure, or Google Cloud account — build a real VPC, deploy a real pipeline. Each lab names only free-tier-eligible resources, ends with checkpoint questions that prove you did the work, and includes a cleanup checklist so nothing keeps running and nothing gets billed.
