Experience Lab

The part a certificate can't show

Each simulation puts you inside a fictional company for a set number of working days. You take the tickets as they come, make the calls, and leave with the artifacts you produced.

Explore Experience Lab
certclue.com/experience
An Experience Lab placement, showing the day's brief and the artifacts due.

Every company, colleague and dataset in a simulation is fictional. A placement is practice, not employment, and completing one is not a job guarantee.

How it works

Four steps, and none of them are behind a paywall.

1

Pick a track

Choose the certification you're sitting, or a Job Ready course if you're after the work rather than the exam. Progress is kept per track, so switching costs you nothing.

2

Practise where it counts

Questions are served in the same proportions as the exam's published domain weightings, so the areas worth the most points get the most of your time.

3

Sit a timed simulation

A full-length, timed exam simulation drawn from a separate pool, so a good score means you know the material rather than that you remember the questions.

4

Show the work

Job Ready courses end in a certificate of completion, and Experience Lab turns one into a simulated placement with artifacts you can put in front of a hiring manager.

More than a question bank

The parts that keep you going: people to study with, something to aim at, and a record of what you did.

What learners say

Submitted after a real practice session or exam simulation, and checked before it appears here.

I learned how appointment reminders, insurance verification, prior authorizations, patient privacy, and call management work together to improve patient access. I also learned to use data to identify problems and recommend practical improvements without making assumptions.

Questions people actually ask

Including the one about whether it is really free. It is.

Is this really free?

Yes, all of it. There is no paid tier and no credit card. Every feature - the full question banks, flashcards, study notes, performance-based questions, games, the study plan and the timed exam simulator - is open to every account.

Which certifications are covered?

18 certification tracks across CompTIA, ISC2, AWS, Microsoft, Cisco, ISACA, PMI and CNCF, including Security+, A+, Network+, ISC2 CC, AWS, Azure, CCNA and CISM. You can switch between tracks at any time and your progress is kept separately for each one.

How much content is there?

14,448 practice questions, 2,691 flashcards, 558 study notes, 1,154 study games and 185 performance-based questions across 18 certification tracks. Every item is reviewed and approved before it is published.

Are the questions weighted like the real exam?

Yes. Each track's question bank is distributed to match the domain weightings in that exam's published objectives document, so a practice session or exam simulation gives you a realistic mix rather than an even spread.

What are Job Ready courses and Experience Lab?

Job Ready courses teach the work itself rather than an exam, and end in a certificate of completion. Experience Lab turns a course into a simulated placement: you work a fictional company's tickets day by day and finish with artifacts you can show. Neither one is a job guarantee, and the certificate certifies completion of the course, not an industry certification.

Do I need to sign up to try it?

No - the free practice tests are open to anyone, no account required, up to 20 graded questions a day. An account removes that daily cap and unlocks the full question banks, flashcards, study notes and the exam simulator.

Where do the questions come from?

They are original questions written from each certification body's publicly published exam objectives. They contain no actual exam content, and we do not host or condone brain dump material.

Can I study with other people?

Yes. Study Groups let you create a group, invite people with a link or by email, and see everyone's progress in one place. Each member picks their own certification track or Job Ready course and their own finishing date, so one group can hold several people sitting different exams. Teams and classes can use an organization instead, with cohorts and assigned exams.

Is there anything that keeps me coming back?

A daily goal and a streak, with a freeze that covers the occasional missed evening. A weekly board ranks people studying for the same certification on questions answered, and you choose whether to appear on it. A weekly recap shows what you actually got through.

Are the reviews on this page real?

Yes. They're submitted by real learners after a practice session or exam simulation, and every one is checked by our team before it's shown here.

Start with a practice test. No account, no card, no catch.
