CompTIA CertMaster Prep 2026

Prepare for six CompTIA certifications in one app — 6,300+ practice questions, every single one with a written explanation. Six exams, one subscription: CompTIA A+ — Core 1 (220-1201) and Core 2 (220-1202) CompTIA Network+ — N10-009 CompTIA Security+ — SY0-701 CompTIA CySA+ — CS0-004 CompTIA PenTest+ — PT0-003 CompTIA SecurityX — CAS-005 What you get: Practice questions with real explanations — 6,300+ questions across the six exams. Every answer tells you why it is right and why the others are wrong, so a missed question turns into something you actually learn. Timed exam simulations — full-length mock exams that follow the real question count and time limit, so exam day is not the first time you feel the clock. Flashcards — 1,900+ cards for the ports, protocols, acronyms and terms you are expected to recall instantly. Nova, your AI tutor — stuck on a question? Ask for a hint that points you in the right direction without spoiling the answer, or ask why an answer was wrong and get the reasoning step by step. Domain analytics — see exactly which objectives are weak and how each domain score moves over time, instead of one overall percentage. Study plan — set your exam date and get a day-by-day plan that adjusts as you work through it. Works offline — questions, flashcards and exam simulations live on your device. No connection needed on the bus, on a plane, or at the test centre car park. Switch between all six exams at any time from inside the app. Progress, streaks and analytics are tracked separately for each one. Whether this is your first IT certification or a specialisation on top of one you already hold, CertMaster keeps the whole path in one place.
