2,600+ flashcards, scheduled so you review the ones you keep forgetting.
Across 18 certification tracks, free, on web and on the mobile app.
Spaced repetition, not a shuffle
A card you find easy comes back in days. One you get wrong comes back today. The schedule is the point: reviewing what you already know is the most comfortable way to waste an evening.
Recall, not reasoning
Cards cover the material that has to be instant rather than worked out. Port numbers, protocol behaviour, framework structure, the acronym behind the acronym. The questions handle judgement.
Split by domain
Every card belongs to an objective, so you can drill the one domain a mock exam just told you was weak instead of the whole deck.
The same deck on your phone
Progress is per account, not per device, so a queue you start on a laptop continues on the mobile app rather than starting again.

Questions about the flashcards
Yes. All of them, with no card and no trial. An account keeps your review schedule, which is the part that makes spaced repetition work at all.
2,600+ across 18 certification tracks, alongside 14,400+ practice questions and 500+ study notes. The figure is read from the database when this page is built.
A question asks you to choose between four plausible answers and explains why three are wrong, which trains judgement. A card asks you to recall one fact with nothing to pick from, which trains speed. An exam wants both, and doing only one of them is the usual reason a mock score stalls.
No. CertClue is online only, on web and in the mobile app. We would rather say that plainly than describe an offline mode that does not exist.
