Why there is no leaderboard, and never will be
Make quiz scores visible to a group and you change what the quiz is for. It stops being a diagnostic — a private, low-stakes way to find out what you don't know — and becomes a performance. The rational response to a public score is to avoid taking quizzes on the topics you're weakest at, which is precisely inverted from what you should do.
So: material is shared, progress is not. Your flashcard review history, your quiz results, your chat, your weak-area chart — private to you, invisible to the group, permanently. This is enforced in the database's access rules, not merely hidden in the interface.
What a shared folder actually gives you
- One canonical set of sources. The syllabus, the readings, the recordings — uploaded once, available to every member.
- Answers that cite pages everyone can open. When someone quotes an answer in the group chat, everyone can check the same citation.
- No seats. You invite people with a code. There is no per-user charge and nobody has to be an admin.
- A shared gap list. If a study guide flags that week 7 has no material behind it, that's a gap for the whole group — and someone will have the file.
