Prepare for Security+, Network+, CySA+, PenTest+, SecurityX, CISA and CISSP with flashcards, timed practice exams, and a tutor that explains every answer.
Pass your cybersecurity certification exam with a plan built around your exam date. DD Academy covers seven exams in one app: Security+ (SY0-701), Network+ (N10-009), CySA+ (CS0-004), PenTest+ (PT0-003), SecurityX (CAS-005), CISA and CISSP.
Every question and flashcard is written to the published exam objectives, and every answer explains why it is right and why the other options are wrong. Each exam keeps its own progress, exam date and readiness score, so you can study more than one.
STUDY YOUR WAY
- Flashcards for every objective, with hints and a multiple-choice mode
- Spaced review that brings cards back before you forget them
- A daily plan built from your exam date, your time, and what you get wrong
PRACTICE LIKE THE REAL THING
- Timed practice exams weighted by the official exam domains, with scenario questions and matching and ordering items
- Domain checks that show which objectives are strong and which need work
- A review pile for questions you missed, until you get them right twice on different days
KNOW WHERE YOU STAND
- A readiness score and an objective-by-objective strength map
- Scores are estimates to guide your study, not predictions
AN AI TUTOR THAT EXPLAINS
- Ask about any card, question, or topic
- Report anything that looks wrong and it can be corrected without an app update
- The tutor can make mistakes, so check important facts
HOW THE CONTENT IS SOURCED
- Questions for each exam are drafted from its official published objectives. The app shows how each exam's content was sourced and reviewed.
REAL THREATS, REAL OBJECTIVES
- Incidents from the Decryption Digest daily brief, linked to the exam objective they relate to
