Hello there,

Your concern about questions appearing outside of exercises or being derived from rationalized chapters is valid. Here's why it might be happening:

1. Increased Critical Thinking Focus : Modern exams often emphasize application-based questions to encourage critical thinking rather than rote memorization. Questions may integrate concepts from chapters or topics not directly covered in the exercises.
   
   

2. Rationalized Syllabus Confusion : Some portions of rationalized syllabi are still considered foundational, and questions may indirectly touch upon those concepts, creating an overlap.
   
   

3. Broader Curriculum Interpretation : Even though certain topics are not explicitly in the exercises, their principles may be implicitly linked to other concepts, which examiners use for creating questions.
   
   

4. Dynamic Question Patterns : Boards and educators sometimes adjust question patterns to align with updated educational objectives, which might make questions feel unfamiliar or challenging.

For better preparation, try to focus on understanding core concepts thoroughly and practicing diverse question types from multiple sources. This will help in tackling such unexpected questions effectively.
