🛠️ Prepare for it — the procedure

This hub is a preparation guide: follow the steps in order. The method is the repo-wide how to prepare a certification; the numbers below (80% per domain, 85% on a full mock) are that method's readiness rule, not a CompTIA figure.

  1. Commit — read exam & objectives, confirm the current exam code and price on CompTIA's page, and set a target date. Plan on roughly 7 weeks at 8–10 hours a week (~54–70 h total, summing the plan's suggested hours) — the study plan breaks that down.
  2. Get the official objectives PDF from CompTIA and fill the coverage map: write each official objective number next to the topic row that covers it, mark any gap, and self-score every row 0–3 before you start (the method explains the scale).
  3. Study weight-first — by weight: 1 → 2 → 3 → 4. For each domain: read the page, do the hands-on items it names (in the CEH lab or on a practice platform), map each attack or control to the attack → defense matrix, then take that domain's practice questions. Log every miss, then drill the flashcard deck with python3 certs/ceh/scripts/quiz.py --deck certs/cysa-plus/exam-prep/flashcards.csv (from the repo root) or import it into Anki.
  4. Rehearse the PBQs — performance-based questions open the exam and eat the clock; the study plan's PBQ section tells you how to drill them. Pace to remember: up to 85 questions in 165 minutes: about two minutes per item, PBQs longer.
  5. Pass the readiness gate — every domain ≥ 80% on a second, spaced attempt; the timed full mock exam ≥ 85%; the glossary · Security+ acronyms automatic; no open weak-area row older than a week.
  6. Exam week — logistics (ID, online-proctoring check or test-centre rules) three days out; final drill of the weak-area log; the exam-day tactics in the CEH exam strategy apply unchanged to CompTIA multiple choice.
  7. After — note CompTIA's continuing-education renewal rule from the objectives page and calendar it; return to the roadmap for the next milestone.

🧭 Where it fits

CySA+ is the detection-and-response analyst credential — the blue-team counterpart to the offensive CEH and PenTest+ hubs, and a natural step after Security+.
