Keep studying across your phone, tablet and desktop. Link the same StudyCert account to merge supported question and glossary study records between the app and desktop web. Mock-exam resume data and device settings remain local to each device. Prepare for CompTIA Security+ with 494 practice questions and 110 key terms. Study coverage · 5 areas • General Security Concepts • Threats, Vulnerabilities, and Mitigations • Security Architecture • Security Operations • Security Program Management and Oversight 1. Build your foundation with key terms Use flashcards to learn meanings, exam context and selection cues. Mark terms as known or not yet known, then revisit unstudied or unfamiliar cards. Edit card content to suit your learning and restore the original when needed. 2. Practice and understand each answer Study in 50-question sets, by domain or by difficulty. Work through single- and multiple-choice questions, then read the explanation for the answer and each option. Choose all, unfinished or wrong questions; shuffle questions and choices; use a study timer; and resume where you left off. From the results of domain study, continue with key terms and related questions in the next domain. 3. Review mistakes and uncertain concepts Choose recent errors, review marks or repeated mistakes on the Review screen and practice them again. Check accuracy by domain alongside the terms you know or still need to learn. The glossary report shows term-learning status and accuracy on related questions together. 4. Check your preparation with a mock exam Practice time management with 90 questions in 90 minutes. Change answers before submission, resume a saved exam and receive grading when time expires. Afterwards, see correct, wrong and unanswered counts, your score and domain results, then revisit mistakes. Practice policy: this mock exam has 90 questions and a 90-minute limit. Answers are equally weighted; passing requires at least 83% correct. This practice result does not guarantee an official exam result. The displayed score reference (750 / 900) is separate from the 83% raw practice target; it is not a calibrated conversion or an official result prediction. Tools that fit your study routine Optional audio study reads terms and meanings aloud. Choose whether to include exam context and selection cues, set repeats and pauses, and control playback with the mini player. In the mobile app, audio can continue in the background and with the screen locked. A study calendar, learning streaks, weekly goals, reminders for unmet goals and light, dark or system themes support your routine. Learning records are managed for each supported language. Some features require paid access. Check the included features and price on the purchase screen. Purchase restoration is supported.
