Study Mode
Drill the facts. Lock in the application.
Four study surfaces, each built for a different job. Flashcards drill recall. Quiz checks application. Study Guide gives you the reference material side-by-side with the practice. PBQs match the real exam format with drag-drop and command-line scenarios.
What it is.
Exam-style quizzes
Real exam-format questions with full explanations. Tag the ones to revisit. Filter by domain, by difficulty, by your weak spots.
Study Guide reference
The full V15-aligned objective notes. Port tables, command references, the things you need to look up mid-quiz. Always one click away.
Performance-based questions
CompTIA exams include performance-based questions. RTJ practices five authored patterns: drag-target, image hotspot, ordered list, validated input, and log picker.
Missed cards circle back
Again sends a card to the end of the deck. Hard keeps it in the current deck for another try. Good and Easy move it to the Got pile.
How it works.
- 01
Pick a surface
Flashcards for recall drill. Quiz when you want exam pacing. Study Guide when you need the reference open. PBQs when you want to practice the actual exam interaction.
- 02
Work through a deck or attempt
Flashcard ratings control whether a card returns in the current deck or moves to the Got pile. Quiz and PBQ attempts show correct answers and explanations so you can target the next pass.
- 03
Practice Exam ties it together
When a domain feels solid, take a full 90-item practice exam. Five PBQs spliced in at unpredictable positions, just like the real exam. Detailed score breakdown after.

Mastery Index on the dashboard
Your correctness on quiz and exam items builds the index. Read it with the evidence-quality label. Flashcard ratings and Study Guide use do not change it.

A user can reach websites by IP address but not by name. Which service is most likely down?

Why
Name resolution is DNS's whole job. IP connectivity working while names fail points straight at it.

Questions.
When do I use Study Mode versus Adventure Mode?+
Adventure teaches a concept through a scenario. Study gives you recall drills, reference material, and exam-format practice. Start with Adventure when the topic is new and you want context. Use Study after, on the bus or between meetings, to rehearse the facts and exam interactions. Both modes use the same objective map, so you can switch without losing the topic thread.
What are PBQs and why do they matter?+
CompTIA uses performance-based questions to test problem solving in realistic settings. CompTIA does not publish a fixed count, position, or five-format taxonomy. RTJ provides five authored practice patterns: drag-target matching, image hotspot, ordered-list reordering, validated text input, and log-entry triage.
What's the Study Guide and how is it different from flashcards?+
The Study Guide is the full V15-aligned reference. Port tables, command references, troubleshooting checklists, the things you need to look up mid-quiz. Flashcards drill the facts as discrete prompts. The Study Guide is the open book. Use both together.
How many cards and PBQs are there?+
A+ Core 1 and Core 2 each have hundreds of flashcards covering every V15 objective. Core 1 PBQs use all five RTJ practice patterns. Core 2 currently uses ordered lists, validated input, and log triage, with no hotspot or drag-target items yet. Network+ and Security+ use all five. Cards and PBQs are authored against the official exam objectives, not scraped from braindump sites.
What's the difference between Flashcards, Quiz, and PBQs?+
Flashcards drill recall. Quiz tests concepts in multiple-choice form. PBQs use interactive practice tasks inspired by the problem solving CompTIA describes. Use all three. Each one builds on the others. Only your quiz and exam results feed your Mastery Index on the dashboard.
Does it work offline?+
Cards load fast and the platform caches recently-used decks for short offline sessions. Long-term we plan a real offline mode for commuters.
