Preplexity is a complete study companion for IT certification exams. One app, 32 certifications across 7 vendors: CompTIA, AWS, Microsoft Azure, Cisco, Google Cloud, ISC2, and ISACA. From A+, Network+, and Security+ to CCNA, AWS Solutions Architect, AZ-104, CISSP, CISM, and CRISC, if it's on your certification path, it's here. OVER 10,000 QUESTIONS, EVERY ONE EXPLAINED Each question comes with a clear explanation of the correct answer and why every wrong answer is wrong. Answer choices are shuffled and balanced so you learn the material, not the option positions. EXAM SIMULATOR Timed, full-length practice exams that mirror the real thing. Question counts, time limits, passing scores, and domain weightings are modeled on each certification's official exam guide. Finish with a pass or fail verdict, a per-domain score report, and for ISACA exams an estimated scaled score. PRACTICE MODE Untimed practice with instant feedback. Weak areas are resurfaced automatically so you review what you miss, and you can report any question from inside the session. SMART FLASHCARDS More than 3,000 spaced-repetition flashcards. Rate each card Again, Hard, or Easy and the deck reschedules itself around what you find difficult. STUDY MATERIALS AND DIAGRAMS Nearly 1,200 concise study topics organized by exam domain, with native diagrams for every certification: process flows, hierarchies, lifecycles, and comparisons built for your phone, not scanned PDFs. READINESS SCORE A per-course readiness score blends your practice results, simulator performance, and study completion, weighted by each exam's official domain percentages, so you know when to book the exam. PICK UP WHERE YOU LEFT OFF Home opens on your next step: continue your last practice session, flashcards or study notes in one tap. TRACK YOUR PROGRESS Per-domain mastery, streaks, XP, badges, exam history, and a study activity calendar show exactly where you stand and what to study next.
