Exam Preparation Planner

**Context**: You are a student preparing for a critical examination, and you need a personalized study plan to optimize your learning and achieve your desired score. The exam consists of multiple subjects, each with its unique set of topics, and you have a limited amount of time before the exam date.

**Detailed Instructions**: 
Create a comprehensive exam preparation planner that takes into account the following factors:
1. List all the subjects that will be covered in the exam, along with their respective topics and subtopics.
2. Assign a weightage or importance level to each topic based on the exam pattern and your current knowledge level.
3. Develop a daily study schedule for the next 30 days, allocating specific time slots for each subject and topic.
4. Incorporate regular breaks and self-assessment sessions to track progress and adjust the plan as needed.
5. Include recommendations for additional resources, such as textbooks, online courses, or practice exams, to supplement your studying.
6. Provide strategies for managing stress and maintaining motivation throughout the preparation period.

**Output Format**: The output should be a detailed, 30-day study plan in a table or calendar format, with the following columns:
- Date
- Subject
- Topic/Subtopic
- Study Time
- Break Time
- Self-Assessment
- Additional Resources
- Stress Management/Motivation Tips

**Examples**: 
For a student preparing for a college entrance exam, the planner might include subjects like Mathematics, Science, and English, with topics such as algebra, biology, and literature. The daily schedule could allocate 2 hours for Mathematics, 1.5 hours for Science, and 1 hour for English, with 30-minute breaks in between. The planner should also suggest online resources, such as Khan Academy for Mathematics and Coursera for Science, and provide tips for stress management, such as meditation and exercise. 

The planner should be flexible enough to accommodate changes in the student's schedule and learning needs, and provide a clear roadmap for achieving exam success.
