Cert Coach — Cloud Certification Study bởi Toby Tinney

Cert Coach is a free study aid for the AWS Certified Cloud Practitioner (CLF-C02) exam. It lives in your Firefox sidebar, so you can study in the gaps in your day without switching windows or opening another tab.

WHY THIS ONE

Most question banks tell you whether you were right. This one tells you why every option is right or wrong — the one you picked, the correct one, and the ones you dismissed. Getting a question wrong is where the learning happens, and a bank that only scores you wastes it.

WHAT YOU GET

220 original questions covering all four exam domains, weighted exactly as the published exam guide weights them: Cloud Concepts 24%, Security and Compliance 30%, Cloud Technology and Services 34%, Billing Pricing and Support 12%.

Both question types the real exam uses — multiple choice, and multiple response where two or more answers are correct and there is no partial credit.

Spaced repetition using Leitner boxes. Answer a question correctly and it moves up a box and returns later. Get it wrong and it drops to box one and comes back sooner. Your weakest material is what you meet first.

A timed practice exam: 65 questions, 90 minutes, sampled at the published domain weighting, with no feedback until you submit and a score broken down by domain.

Plain-English explanations. Every cloud term is defined the first time it appears, because the exam assumes less prior knowledge than the internet does.

PRIVACY

This add-on makes no network requests. None. Your progress is stored on your own device and never leaves it. There is no account, no sign-in, no analytics and no tracking of any kind.

It requests one permission and no more: storage, to save your progress locally. It has no access to any web page you visit — it cannot read them, and it never tries.

WHO IT IS FOR

Business owners and IT managers who need to understand what they are buying. Career changers working towards a first cloud certification. Anyone who has heard of "the cloud" and wants to stop nodding along.

The Cloud Practitioner is the only AWS certification with no assumed hands-on experience, which makes it the right first step.

FREE, WITH NO CATCH

No paid tier, no trial, no upgrade prompt. It is published by Speaking of Clouds, a free resource for cloud computing at speakingofclouds.com, and it exists to be useful.
