Study
Work through the Jeremy's IT Lab CCNA course in order — videos, transcripts and topic-organized resources keep the source material easy to navigate.
- [02]
Review
Flashcards return on a spaced-repetition schedule computed in your browser, focusing review where recall is weakest.
- [03]
Apply
Applied networking exercises and CLI drills — written by OZTEK and separate from the source course — turn recognition into working skill.
Your progress and data
- Progress is stored in your browser on this device — no account and no automatic sync between devices.
- Export and import let you move progress between devices or keep a backup.
- Clearing browser data or losing the device can make progress unavailable. Export a backup regularly.
- Checkpoint answers are graded by a stateless service, and video and source links contact external providers, so those actions require a network connection.
How it is built
CCNA Study is a web application whose engineering follows the learner workflow.
Structured course content
A course manifest maps topics, videos and resources so the source material stays organized and navigable.
Browser-local persistence
Progress and review state are stored in IndexedDB; export and import provide transfer and backup.
FSRS scheduling
The ts-fsrs algorithm computes each card's next review from your actual recall performance.
Stateless checkpoint grading
Checkpoint answers are sent to a separate grader that returns a result without retaining a learner history.
Sources and independence
- Course organization, videos, transcripts and card content come from Jeremy's IT Lab — CCNA Study does not claim authorship of that material.
- The application, applied exercises and CLI drills are OZTEK's own work, separate from the source course.
- CCNA Study is not affiliated with or endorsed by Jeremy's IT Lab or Cisco.
