Answer 1

commit() your editor before do apply()

 if(scoreToUpdate > correct){
        correct = scoreToUpdate;
        SharedPreferences sharedPreferences = getSharedPreferences(SCOREPREFERENCE,MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putInt(CORRECT,correct);
        editor.commit(); //insert here
        editor.apply();
        }

    private void updateWrongAnswer(int scoreToUpdate){
        if(scoreToUpdate > wrong) {
            wrong = scoreToUpdate;
            SharedPreferences sharedPreferences = getSharedPreferences(SCOREPREFERENCE,MODE_PRIVATE);
            SharedPreferences.Editor editor = sharedPreferences.edit();
            editor.putInt(WRONG,wrong);
            editor.commit();  //insert here
            editor.apply();
        }
    }
