Throughout the Official Mark Calculator, courses that are deemed equivalent to other courses are used in various contexts. To ensure the right equivalencies are considered, the calculator first identifies the equivalent courses that may need to be considered.

To identify Regular Equivalencies that should be considered, the Official Mark Calculator first identifies a list of courses the student has passed (along with the school years in which they passed the course). This list of passed courses is built by iterating through the Course Enrolments, Evaluated Marks, and Diploma Exam Marks for the student.

For each Course Enrolment, if the Course Enrolment includes an approved passing mark, the course code is identified as a course that the student passed in the school year of the associated section.

• Passed Course . Course Code = Course Enrolment . Course Code
• Passed Course . School Year = Course Enrolment . Section . Section School Year

For each Evaluated Mark, if the Evaluated Mark includes an approved passing mark, the course code is identified as a course that the student passed in the school year of the evaluation.

• Passed Course . Course Code = Evaluated Mark . Evaluated Mark Course Code
• Passed Course . School Year = Evaluated Mark . Evaluated Mark School Year

For each Diploma Exam Mark, if the Diploma Exam Mark includes a passing mark, the course code is identified as a course that the student passed in the school year when they wrote the exam..

• Passed Course . Course Code = Diploma Exam Mark . Diploma Exam . Course Code (Diploma Exam)
• Passed Course . School Year = Diploma Exam Mark . Diploma Exam . School Year (Diploma Exam)

Once all the passed courses have been identified, the calculator identifies a list of courses that are deemed equivalent to the passed courses. This is done by iterating through the list of passed courses. For each school year in which the student passed a course, the calculator identifies the courses that are deemed equivalent to the course the student passed. This is done by finding Course Relationshipss that meet the following criteria:

• Course Code is the same as the Course Code of the course the student passed.
• Relationship Type (Course) is for a Regular
• First School Year (Course Relationship) is the same as or earlier that the School Year in which the student passed the course.
• Last School Year (Course Relationship) (if provided) is the same as or later than the School Year in which the student passed the course.

Based on the Course Relationship found, a list of potentially equivalent courses is created by adding each of the Related Courses is the Course Relationship to the list of potentially equivalent courses.

• Potential Equivalent . Passed Course Code = Passed Course . Course Code
• Potential Equivalent . School Year = Passed Course . School Year
• Potential Equivalent . Equivalent Course Code = Course Relationships . Related Courses . Course Code

By matching the list of { Potential Equivalent . Passed Course Code } against the list of { Passed Course . Course Code }, the potentially equivalent course will be considered a valid equivalent course if the list of { Passed Course . School Years } for the course code is the same as the list of { Potential Equivalent . School Years } for the same course code.

Each potentially equivalent course that passes this validation is then added to the final list of equivalent courses:

• Equivalent Course . Passed Course Code = Potential Equivalent . Passed Course Code
• Equivalent Course . Equivalent Course Code = Potential Equivalent . Equivalent Course Code

When needed, the official mark calculator can then reference this list of equivalent courses.

Consider the following set of course enrolments:

and the following set of evaluated marks:

The list of passing courses would include:

Considering the following course relationships for ABC1111:

The list of potentially equivalent courses would include:

When comparing the school years for the passed courses against the list of school years for the potentially equivalent courses:

Therefore, the validated list of equivalent courses includes:
