Subject-based study hub
VietJack organizes school content around subjects such as literature, math, physics, chemistry, biology, history, geography, technology, English, and other classroom areas. The home screen uses clear icons and tabs for quick movement between study topics.
This layout is useful for students who want fast access to lessons without searching across many websites. A subject grid also helps parents or learners find the right material by class or topic.
This gives the section a clearer user value by connecting the main feature to a concrete mobile use case, session goal, or replay reason.
Livestreams, Q&A, and saved lessons
The app includes recent livestream content, a question-and-answer area, saved lesson sections, bookmarks, feedback, and account options. These tools support both passive review and active study questions.
Students can use Q&A and bookmarks to keep track of weak areas. Account features may improve personalization, but users should understand what information is saved before relying on it for regular study.

Ads and study permissions
The package declares advertising identifiers, camera, contacts, microphone, notifications, network access, storage, wake-lock, and push messaging behavior. These can support ads, account features, question submission, media input, and reminders.
Camera, contacts, and microphone access should be granted only when a study feature clearly needs them. Younger users should have ad and account settings reviewed by an adult.
