How Adaptive Question Selection Works
- No Repeats Within a Session: Questions are sampled without replacement inside each session so you never get the same question twice in one session.
- Unseen & Missed Priority Pool: Adaptive sessions draw from questions you haven't seen yet (
8.0xbase weight) and questions you got wrong previously (14.0x–24.0x+boost) before ever revisiting questions you already answered right. - Mastery Decay: Consecutive correct answers reduce a question's sampling weight so you focus on new and weak areas.
- Bookmarks: Starred questions receive an automatic
+4.0xpriority boost.
