Questions that test whether you understand, not whether you remember.

How it will work

Two modes

Training puts the concepts you have got wrong before at the front of the queue, corrects you immediately, and runs without a clock. Exam shuffles everything, times you, and holds every correction until the end, because learning to sit with uncertainty is part of what the real exam measures.

Spaced repetition, on concepts

A concept you get wrong comes back in the next round. A concept you get right repeatedly is spaced out further each time until it leaves rotation. Crucially, progress belongs to the concept, not to the question: get the same idea right through three different phrasings and you have actually learned it. Answer choices are reshuffled every time they are shown, so position never becomes the answer.

An honest "not sure" button

Every question can be answered while flagged as a guess. A flagged answer counts as wrong even when it is right, and the concept returns. Lucky guesses are the main reason candidates feel ready and are not.

A diagnostic that points somewhere

At the end of a session you get a breakdown by official exam domain, not a single percentage, along with what to revise first. A score of 71% is not information. "You are losing points in Troubleshooting, which is 30% of the CKA" is.
