CertPrepXStudying hard isn't enough if you can't measure readiness.
Most candidates don't fail because they didn't study. They fail because they don't know where they're weak. CertPrepX finds weak domains, resurfaces due questions, and measures readiness before exam day.
A number you can actually trust.
Most prep tools hand you a raw percentage. We model the real exam, so your score means what it says, and tells you when you're genuinely ready.
Calibrated to the real cut score
Scored on each exam's actual scale and passing standard — CISA's 200–800 with a 450 cut, CISSP's 0–1000 — not an arbitrary percentage.
Weighted by official domains
Your score follows the published blueprint weights, so a weak high-weight domain moves the needle more than a strong minor one.
Recalibrated on every answer
Each question updates the estimate and confidence tightens as you practice — so "ready" means ready, not a lucky streak.
Practice, find your gaps, close them, repeat.
Practice
Certification-focused question banks.
Analyze
Domain analytics surface weak areas.
Review
Spaced repetition on due items.
Improve
Targeted drills close the gaps.
Pass
Readiness confirms you're ready.
Every answer turns into a plan.
The readiness score tells you whether you'd pass. These work out exactly what to do next.
Domain-by-domain mastery
Every answer feeds a per-domain mastery score that blends accuracy, recency, and question difficulty — not just raw percent correct.
Weak areas surfaced for you
Mastery is weighted by each domain's official exam weight, so the gaps that cost you the most marks rise to the top automatically.
Your next move, decided
Your data becomes one clear next action and a study plan that shifts toward your weakest domains as you go.
Nothing slips through
Questions you miss or feel unsure about are scheduled for spaced review right before you'd forget them.

Can I buy CertPrepX for my team?
Yes. Team plans are billed per seat (5-seat minimum) on monthly, quarterly, or annual cycles. The owner gets an invite code to share, can add or remove seats anytime with prorated billing, and can revoke access to free up a seat. No annual contract — cancel anytime, and contact us about volume discounts for larger rollouts.
Can I give CertPrepX as a gift?
Yes. Buy a 1-month, 3-month, or 1-year gift and you'll get a redeemable code to share. The recipient just enters the code to unlock Premium — no email exchange needed. If they already have a subscription, the gift adds time on top rather than replacing it.
Are the questions updated for the current exam version?
Yes. Our curriculum team reviews and audits the question bank monthly so it stays aligned with the latest certification standards and job-practice domains.
How does CertPrepX know when I'm ready to pass?
Your readiness score is calibrated to the real exam’s scoring scale, weighted by each domain’s exam weight, and recalibrated on every answer — so it reflects exam-day performance, not just raw percent correct.
What is spaced repetition and how does it help?
The app tracks which questions you miss or feel unsure about and automatically schedules them for review at increasing intervals. You spend your time on genuine weak spots instead of re-studying what you already know.
Can I sync my study plan to my calendar?
Yes. Set your exam date and weekly hours and CertPrepX builds an adaptive day-by-day plan you can subscribe to from Google Calendar, Apple Calendar, or Outlook. The feed stays in sync as your plan adapts, and you can revoke access anytime.
Can I export my data?
Yes. You can download everything we store about you — profile, sessions, scores, progress, and notes — as a single JSON file from your account settings at any time, in line with GDPR data portability.
Exam prep should feel clear, measurable, and achievable.
