These inner braces limit the scope of the variables declared within them.

System.out.println();
System.out.println("Enter all of the exam scores.");
sum=0;
int NumberOfA = 0;
int NumberOfB = 0;
int NumberOfC = 0;
int NumberOfD = 0;
int NumberOfF = 0;
next = keyboard.nextInt();
score = keyboard.nextInt();
grade = keyboard.next();
}

So outside them, the variables cannot be resolved.

sum = sum + next;
numberOfA++;
numberOfB++;
numberOfC++;
numberOfD++;
numberOfF++;

Remove the inner braces.
