Nuru, Good morning. Below is one of the thought process. You can have three classes 1. To store the Subject Details, 2. To store Student Details, this class will expose a method to Calculate Gpa, and 3. List of Students. Please review and advise if this works. Many thanks. public class SubjectDetails { public int Id { get ; set ; } public string Name { get ; set ; } public double Mark { get ; set ; } public string Grade { get ; set ; } } public class Student { public int Id { get ; set ; } public string Name { get ; set ; } public List Subjects { get ; set ; } public double GetGpa() { // Calculate Using the Subjects Property return 1.2; } } public class Students { public int Id { get ; set ; } public List AllStudents { get ; set ; } }
