Trouble getting input for object array

I am trying to create a class that receives data about a person's name, exam subject, and exam score. I have these classes so far:

APExam:

public class APExam {
   //instance variables
   private String mySubject;
   private int myScore;
   
   //constructors
   public APExam(String subject, int score) {
      mySubject = subject;
      myScore = score;
   }
   public APExam() {
      mySubject = "";
      myScore = 1;
   }
   
   //getters and setters
   public void setSubject(String s) {
      mySubject = s;
   }
   public String getSubject() {
      return mySubject;
   }
   public void setScore(int score) {
      myScore = score;
   }
   public int getScore() {
      return myScore;
   }
   
   //compareTo
   public String compareTo(int s) {
      if(myScore == s)
         return "Scores are equal.";
      else if(myScore > s)
         return "The first score is greater than the second score.";  
      else 
         return "The second score is greater than the first score.";
   }
   
   //equals
   public boolean equals(String str) {
      return mySubject.equals(str);
   }
   
   //toString
   public String toString() {
      return "Subject: " + mySubject + "\nScore: " + myScore;
   }
}

APStudent:

public class APStudent {
   //instance variables
   private String myFirstName;
   private String myLastName;
   private ArrayList<APExam> myExams = new ArrayList<APExam>();
   
   //constructors
   public APStudent(String fname, String lname) {
      myFirstName = fname;
      myLastName = lname;
   }
   public APStudent() {
      myFirstName = "";
      myLastName = "";
   }
   
   //getters and setters
   public void setFirstName(String fname) {
      myFirstName = fname;
   } 
   public String getFirstName() {
      return myFirstName;
   }
   public void setLastName(String lname) {
      myLastName = lname;
   }
   public String getLastName() {
      return myLastName;
   }
   public ArrayList<APExam> getExams() {
      return myExams;
   }
   
   //addExam
   public void addExam(APExam ex) {
      myExams.add(ex);
   }
   
   //computeExamAverage
   public double computeExamAverage(List<APExam> exams) {
      int sum = 0;
      for(int i = 0; i < exams.size(); i++) {
         sum += exams.get(i).getScore();
      }
      return (double) sum / exams.size();
   }
   
   //findHighestExamScore
   public int findHighestExamScore(List<APExam> exams) {
      int max = exams.get(0).getScore();
      for(APExam ex : exams) {
         if(ex.getScore() > max) {
            max = ex.getScore();
         }
      }
      return max;
   }
   
   //numberOfFives
   public int numberOfFives(List<APExam> exams) {
      int fiveCount = 0;
      for(APExam ex : exams) {
         if(ex.getScore() == 5) {
            fiveCount++;
         }
      }
      return fiveCount;
   }
}

ArrayListTest:

public class ArrayListTest {
   public static void main(String[] args) {
      //instance variables
      final String QUIT = "end";
      Scanner sc = new Scanner(System.in);
      ArrayList<APExam> myExams = new ArrayList<APExam>();
      APStudent student = new APStudent();
      String fname, lname, sub, input = "";
      int score;
      
      //prompt for info
      System.out.print("Enter first name: ");
      fname = sc.nextLine();
      student.setFirstName(fname);
      System.out.print("\nEnter last name: ");
      lname = sc.nextLine();
      student.setLastName(lname);
      while(!input.equals(QUIT)) {
         APExam ap = new APExam();
         System.out.print("\nEnter exam subject or 'end' to quit: ");
         input = sc.nextLine();
         sub = input;
         ap.setSubject(sub);
         System.out.print("\nEnter exam score: ");
         score = sc.nextInt();
         ap.setScore(score);
         student.addExam(ap);
         sc.nextLine();
         
      }
      
      //display information
      System.out.println(student.getExams());
      System.out.println("Name: " + student.getFirstName() + " " + student.getLastName());
      System.out.println("Exam average score: " + student.computeExamAverage(myExams));
      System.out.println("Highest score: " + student.findHighestExamScore(myExams));
      System.out.println("Number of fives: " + student.numberOfFives(myExams));
      
      System.out.println();
      
      
      for(int i = 0; i < myExams.size(); i++) {
         System.out.println(myExams.get(i));
      }
      
      //prompt for search
      System.out.println("1 sequential search" 
                        + "\n2 binary search"
                        + "\n3 exit");
      input = sc.nextLine();
      while(!((input.equals("1") || input.equals("2") || input.equals("3")))) {
         switch(input) {
            case "1":
               sequentialSearch(myExams, 3);
               break;
            case "2":
               binarySearch(myExams, 2);
               break;
            case "3":
               break;
         }
      }
   }
}

For some reason in the ArrayListTest class it doesn't create an APExam object with the inputted scores and subjects. Is there something wrong with the while loop? Or is something else wrong?
