KCSA Exam Timing and Error Budget
KCSA is 60 questions in 90 minutes at 75%, the highest pass mark on this site. Two numbers follow from that and they decide everything else on the day. This guide computes them, sets each domain against the error budget, and measures what a question physically looks like - all from the real 889-question bank.

Written against the versions above. Every number here is computed from the catalogue and the question bank at run time rather than typed in, so it cannot drift from the exam this site sells.
