We’re developing a grading system for a school with multiple levels (e.g., elementary, middle school, high school) and various subjects within each level (n subjects < 200). The challenge is that:

Dynamic Marking Schemes:
Each subject can have its own unique marking pattern. This pattern might involve factors like:

• Score: The base score achieved by the student.
• Additional Data: Parameters influencing the marking, such as:
  1. Date of exam (e.g., scaling for particularly difficult exams)
  2. Age of candidate (e.g., adjustments for younger students)
  3. Location (e.g., accounting for regional variations)
  4. Monthly income (e.g., socio-economic considerations)
• Shared Marking Schemes: Some marking schemes might be applicable across multiple subjects within a level or even across different levels.
• Scalability: The solution should efficiently handle a moderate number of subjects (less than 200) while allowing for future growth.

Desired Solution:

We’re seeking a Java solution that effectively addresses these challenges. Ideally, the solution should:

• Flexibility: Allow for defining various marking schemes with different factors influencing the final marks.
• Reusability: Minimize code duplication by enabling shared marking schemes across subjects and levels.
• Maintainability: The code should be well-structured and easy to understand for future modifications.
