Frequently asked questions
Straight answers about the GRID exam, the questions, pricing, the free trial, and how this fits your prep.
The GRID exam spans 7 domains - Active Defense in an ICS Environment, Detection in an ICS Environment, Incident Response in an ICS Environment, Monitoring in an ICS Environment, Threat Hunting and Analysis in an ICS Environment, Threat Intelligence in an ICS Environment, and Visibility and Asset Awareness in an ICS Environment. Every practice question maps to one of them, so you train on exactly what's tested.
The GIAC Response and Industrial Defense (GRID) exam has 75 questions and is completed in 2 hours. Our timed practice tests mirror that length and pacing, so exam day feels familiar.
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the GRID exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
No. GRID Exam Prep is an independent study resource for GIAC Response and Industrial Defense (GRID). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.
Every paid plan unlocks the full bank of 1,000+ practice questions covering all 7 GRID domains - Active Defense in an ICS Environment, Detection in an ICS Environment, Incident Response in an ICS Environment, Monitoring in an ICS Environment, Threat Hunting and Analysis in an ICS Environment, Threat Intelligence in an ICS Environment, and Visibility and Asset Awareness in an ICS Environment. You can practice the whole bank, filter by domain, or run a timed, domain-balanced exam simulation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Chat with us any time - the 24/7 support chat in the corner of every page gives instant answers about plans, access, and billing. Prefer email? The contact link is in the footer. Payments are processed securely by Polar, and active customers can download an invoice from their profile page.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email us from the contact link in the footer and it'll be sorted out.

Real feedback from GRID candidates on Reddit.
"wasnt sure this site would be worth it but the practice questions actually matched the style of the real thing pretty well. the incident response scenarios especially. passed with a bit of room to spare, which i definately did not expect given how late i started studying."
"i put off studying for like three weeks and then kind of panicked. found gridexam.com somewhere in this sub and just worked thru the question bank every night for the last stretch."
"tbh i was skeptical. ended up using it alongside my notes and it was fine. the asset visibility questions were solid prep. nothing fancy but it covered what it needed to."
