  • void viewSpecificExamScore(List<Assessment> listOfGrades, Student student)L142

    Pick a course and an exam type, then print that one score.

  • void viewAllGradesForCourse(List<Assessment> listOfGrades, Student student)L94

    Pick one of your courses and print every exam type and score in it.

  • void viewTotalAverageGrade(List<Assessment> listOfGrades, String studentId, String courseCode)L124

    Average every score for a student in one course.
