Android : Send the same data to two different activities in Android

I have a quiz game of 5 questions that shows results as a rating bar that I also want to show on the start of the quiz. Here is my quiz activity where the score "int" is generated.

public class QuizActivityt1 extends Activity {
List<Question> quesList;
int score=0;
int qid=0;
Question currentQ;
TextView txtQuestion;
RadioButton rda, rdb, rdc;
Button butNext;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_quiz);
    DbHelpert1 db=new DbHelpert1(this);
    quesList=db.getAllQuestions();
    currentQ=quesList.get(qid);
    txtQuestion=(TextView)findViewById(R.id.textView1);
    rda=(RadioButton)findViewById(R.id.radio0);
    rdb=(RadioButton)findViewById(R.id.radio1);
    rdc=(RadioButton)findViewById(R.id.radio2);
    butNext=(Button)findViewById(R.id.button1);
    setQuestionView();
    butNext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RadioGroup grp=(RadioGroup)findViewById(R.id.radioGroup1);
            RadioButton answer=(RadioButton)findViewById(grp.getCheckedRadioButtonId());
            Log.d("yourans", currentQ.getANSWER()+" "+answer.getText());
            if(currentQ.getANSWER().equals(answer.getText()))
            {
                score++;
                Log.d("score", "Your score : "+score);
            }
            if(qid<5){
                currentQ=quesList.get(qid);
                setQuestionView();
            }else{
                Intent intent = new Intent(QuizActivityt1.this, ResultActivityt1.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b);
                startActivity(intent);
                finish();
            }
        }
    });
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_quiz, menu);
    return true;
}
private void setQuestionView()
{
    txtQuestion.setText(currentQ.getQUESTION());
    rda.setText(currentQ.getOPTA());
    rdb.setText(currentQ.getOPTB());
    rdc.setText(currentQ.getOPTC());
    qid++;
}

}

I was able to send it to send it via intent the result activity and then show it as a rating bar as the following.

public class ResultActivityt1 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_result);
    //get rating bar object
    RatingBar bar=(RatingBar)findViewById(R.id.ratingBar1); 
    bar.setNumStars(5);
    bar.setStepSize(0.5f);
    bar.setEnabled(false);
    //get text view
    TextView t=(TextView)findViewById(R.id.textResult);
    //get score
    Bundle b = getIntent().getExtras();
    int score= b.getInt("score");
    //display score
    bar.setRating(score);
    switch (score)
    {
        case 1:
        case 2: t.setText("Oopsie! Better Luck Next Time!");
        break;
        case 3:
        case 4:t.setText("Hmmmm.. Someone's been reading a lot of trivia");
        break;
        case 5:
        case 6:t.setText("Who are you? A trivia wizard???");
        break;
    };
}

So far so good, but what I have attempting to do is to make that intent go also on my Main activity to show the score elsewhere, here is my main activity:

public class Tech extends Activity {

Button T1,T2,T3;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tech);
    RatingBar rbt1=(RatingBar)findViewById(R.id.rbt1);
    rbt1.setNumStars(5);
    rbt1.setStepSize(0.5f);
    rbt1.setEnabled(false);;
    RatingBar rbt2=(RatingBar)findViewById(R.id.rbt2);
    rbt2.setEnabled(false);
    RatingBar rbt3=(RatingBar)findViewById(R.id.rbt3);
    rbt3.setEnabled(false);
    T1 = (Button)findViewById(R.id.T1);
    T2 = (Button)findViewById(R.id.T2);
    T3 = (Button)findViewById(R.id.T3);

    T1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {


            Intent myIntent = new Intent(Tech.this, QuizActivityt1.class);
            //Optional parameters
            startActivity(myIntent);
        }
    });

    T2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent myIntent = new Intent(Tech.this, QuizActivityt2.class);
            //Optional parameters
            startActivity(myIntent);
        }
    });

    T3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent myIntent = new Intent(Tech.this, QuizActivityt3.class);
            //Optional parameters
            startActivity(myIntent);


        }
    });
}

I know this may seem like an easy question, but unfortunately I am a beginner and I tried many workarounds I found similar to my case.
