WHAT'S INSIDE

- Flashcards that resurface based on how well you know them
- Study notes with exam tips and mnemonics
- Performance-based questions: drag-and-drop, ordered steps, categorisation
- A timed exam simulator that mirrors the real exam's length and domain weighting
- A readiness score built from your own accuracy, not a guess
- Quick knowledge-check games for spaced recall

JOB READY COURSES
- 36 role-based courses that teach the work, not only the exam: SOC analyst,
IT support technician, data analyst, KYC/AML analyst, QA tester, junior
developer and more
- Read the lessons in the app, with knowledge checks as you go
- Courses finish on certclue.com, where you submit the projects that earn
the certificate

HONEST BY DESIGN
Every question is original, written to the published exam objectives. We do not host or condone leaked or "brain dumped" exam content, and passing a practice exam here is not a guarantee of passing the real one. Where a vendor does not publish an official passing score (Cisco's CCNA, for example), we say so plainly instead of inventing one.

CertClue is an independent study resource and is not affiliated with, authorised, endorsed by, or sponsored by CompTIA, ISC2, Amazon Web Services, Microsoft, Cisco or ISACA.
Free practice tests, flashcards and exam sim for 11 IT certifications.

What’s new

Your streak now has a week view, and a freeze that covers one missed day so an ordinary busy Tuesday does not reset it.
New: a weekly leaderboard, a recap of your week, and a moment when a domain passes 80 percent.
Faster throughout. Screens open on your numbers instead of a loading placeholder, and submitting an answer no longer blanks the screen.
Control Match is now a real pairing board. Invite a study partner from your profile.
Fixes to Help and support, and to Trajectory.
