Computer Adaptive Testing
Mirrors the real ISC² CISSP exam. Every answer updates your ability estimate (θ) using Item Response Theory, then the engine selects the next question closest to your current ability level — maximizing measurement precision.

How it works

  • Starts at θ = 0 (medium difficulty)
  • Correct answer on hard question → θ rises faster
  • Wrong answer on easy question → θ drops faster
  • Domain weights enforced (ISC² blueprint)
  • 125–175 questions, stops at confidence threshold

What you get

  • Live θ ability score after every question
  • PASS/FAIL simulation at θ ≥ 0.5
  • Per-domain strength: Strong / Moderate / Weak
  • Explanation + distractor rationales revealed on confirm
  • Full session stored in Supabase for analytics
