Explanation / Answer

The code is not fully understandasbale and is incomplete.

Anyways with the provided code, I could guess there is an error with theHighest code. Please modify your code as below and let me know

public GradedActivity getHighest()
   {
       GradedActivity highest = grades[0];
      
       for(GradedActivity current : grades)
       {
           if(current.getScore() > highest.getScore())
           {
               highest = current;
           }
       }
      
       return highest;
   }
