Web payment note: RevenueCat web checkout uses Stripe and may show cards plus wallet options such as Google Pay. If checkout or renewal does not complete, try another available web payment method first. Customers using India-issued payment methods may run into extra issuer authentication or recurring-payment limits; if web checkout still fails, subscribe through the Apple App Store, Mac App Store where available, or Google Play for the same app family, then sign in with that app-family account and tap Refresh.

How our practice is built: Mastery Exam Prep uses original, blueprint-aligned questions, public samples from maintained practice banks where available, and clear labels for live practice pages, retired-exam guidance, and replacement guidance. See why practice-first prep matters, or read the practice methodology.

Access and account help

Start on web for zero-install practice, or use IT Mastery on iPhone or Android. Sign in with the same IT Mastery account on each supported device so access and progress stay together.

Web sign-in supports Email/Password, Apple, and Google. If you buy on web, sign in on mobile with the same IT Mastery Email/Password account.

If paid content looks locked, do not purchase again:

Confirm that you opened IT Mastery and signed in with the account used for the purchase.
Open My Profile & Stats and tap Refresh.
Use Restore Purchases only when the purchase came from the App Store or Google Play.
Follow the locked-access steps if access is still missing.

Hands-on exam preparation

Some Linux and Kubernetes certifications, including Red Hat exams, CKA, CKAD, CKS, and LFCS, require practical lab work. IT Mastery objective questions can support knowledge review and decision practice, but they do not replace hands-on preparation for a performance-based exam.
