ImprovementRandom quizzes now cover a broader range of exercises
Tagged exercises and randomized quizzes now sample from the full set of available candidates instead of favoring a subset. This makes review more balanced.
Exercises that were previously less likely to appear can now be reached, reducing repetition of the same questions.
Random quizzes cycle through the full candidate range regardless of where sampling starts.
The lesson knowledge for BB 3bet rules was also aligned with the verified step thresholds.
