Hardest KCSA topics, from learners' first answers
Last computed
These are the KCSA subdomains where GoldenKube learners most often got their first answer wrong. 96 learners gave 882 first answers on KCSA; subdomains with fewer than 20 answers are left out.

How these numbers are made
Every answer given in GoldenKube practice is stored. Once a day the answers are aggregated per subdomain, and only each learner's first answer to each question counts, so the review repeats of a missed question do not push its topic up the list. The wrong rate is the share of those first answers that were wrong. The last-90-days column repeats the calculation for first answers given in the past 90 days.
Read the table with two limits in mind. The learners are self-selected: people who chose to practise KCSA here, at every stage of preparation, not a sample of exam candidates. And practice is not the exam: a high wrong rate can mean a hard topic, a hard set of questions in this bank, or both. It says nothing about how the real exam is scored.
