3. Rule 3: Course Availability

Our PyKE expert system further enhances the course selection process through the implementation of Rule 3, which revolves around course availability. This rule functions as a scheduler's ally, meticulously cross-referencing the recommended courses with the student's intended enrollment period. By doing so, it safeguards against the frustration of desiring courses that may not align with the student's timeline, ensuring that the courses suggested are indeed accessible and can be seamlessly integrated into the student's academic plan.

```python rule course_availability: for course in student.recommended_courses: if course not in student.available_courses: retract course from student.recommended_courses ```

4. Rule 4: Course Difficulty

In the realm of academic excellence, Rule 4 takes center stage by factoring in the student's historical academic performance. It scrutinizes the level of difficulty associated with each recommended course, ensuring that these recommendations align harmoniously with the student's capabilities and past achievements. This thoughtful approach fosters a balanced and supportive learning environment, steering students away from overwhelming course loads and guiding them towards courses that offer an appropriate level of academic challenge. These two rules, like the cogs in a well-oiled machine, work in tandem to optimize the course selection process, prioritizing accessibility, and academic growth.

```python rule course_difficulty: for course in student.recommended_courses: if course.difficulty > student.max_difficulty: retract course from student.recommended_courses ```

5. Rule 5: Interest and Passion

The journey to informed course selection continues with Rule 5, emphasizing the pivotal role of student interests and passions. Here, our PyKE expert system dons the hat of an enthusiastic mentor, actively promoting the selection of courses that resonate with a student's genuine interests.
