Based on the limited information provided, it seems you are asking about the difficulty level of question papers and availability of question banks or important questions for an exam or course.

However, without knowing the specific exam or course you are referring to, it's difficult to provide accurate details. The difficulty level and availability of study materials can vary greatly depending on the exam conducting body, institution, and the nature of the subject.

In general:

- Question paper difficulty: It's subjective and depends on the exam pattern, syllabus, and the level of the exam. Reputed exams usually maintain a consistent difficulty level year-over-year.

- Question banks: Many institutions provide question banks or previous year question papers to help students prepare. However, the availability and coverage of these materials differ.

- Important questions: Some institutions share important topics or frequently asked questions to guide students' preparation. But again, this is not a universal practice.

My advice would be to refer to the official website or prospectus of the specific exam or course you are interested in. You can also reach out to the exam conducting body or institution for more precise information regarding the exam pattern, study materials, and other important details.
