The blueprint above spans 6 domains — read the weightings as your study budget. A domain carrying of the score deserves a matching share of your week, while lighter ones like Troubleshooting and Maintenance can be maintained rather than marathoned. Work the full topic list above domain by domain, and let the percentages decide where your practice time goes first.

All three versions carry the same 138 expert-written questions — you're choosing a study environment, not a content tier:

  • PDF version — printable and instantly downloadable, built for reading anywhere and annotating by hand.
  • Desktop Test Engine — Windows software that recreates the real exam atmosphere, with two practice modes and full offline access.
  • Online Test Engine — any browser on Windows, Mac, Android, or iOS, with test history and performance review built in.

Most candidates mix formats — PDF for reading, an engine for timed rehearsal.

Support runs around the clock: free online consultation whenever you need it, remote guidance for installation or usage issues, and patient email answers to content questions. On privacy, the stance is rigid — transactions are secured by McAfee security services, purchase information is never disclosed to third parties, and no spam or telemarketing follows your order.

Work in passes rather than one grind. First pass: move through the 138 questions untimed, mapping weak domains against the blueprint above. Second pass: timed engine sessions, reviewing every error the same day while the reasoning is fresh. Final pass: re-test only your flagged questions until they stop being wrong. Book the exam when your timed scores hold steady, not when your calendar gets impatient.
