Score variable counter is off

Hello all,
I have a multiple choice quiz with 10 questions. When I go through the quiz and pick the 10 answers when I get to the results it says 6 out of 10 instead of 10 out of 10.

Here are the questions:

package com.example.dan.biblechallenge;

import android.content.Intent;
import android.os.CountDownTimer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.List;
public class QuestionActivity extends AppCompatActivity implements View.OnClickListener{
int score = 0;
Button button;
int qid = 0;
Button btnA, btnB, btnC, btnD;
TextView txtQuestion;
List whyQuesList;
QuestionsTable currentWhyQ;
CountDownTimer countDownTimer;
TextView textV;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.question);
MySQLiteHelper db = new MySQLiteHelper(this);
whyQuesList = db.getAllWhys();
currentWhyQ = whyQuesList.get(qid);
txtQuestion = (TextView) findViewById(R.id.txtViewQuestion);
final TextView myTimer = (TextView) findViewById(R.id.txtViewTimer);

    btnA = (Button) findViewById(R.id.btnOptionA);
    btnA.setOnClickListener(this);
    btnB = (Button) findViewById(R.id.btnOptionB);
    btnB.setOnClickListener(this);
    btnC = (Button) findViewById(R.id.btnOptionC);
    btnC.setOnClickListener(this);
    btnD = (Button) findViewById(R.id.btnOptionD);
    btnD.setOnClickListener(this);
    setWhyQuestionView();



}

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btnOptionA:
            if (currentWhyQ.getAnswer().equals(btnA.getText())) {
                score += 1;
            }
            if (qid < 10) {
                currentWhyQ = whyQuesList.get(qid);
                setWhyQuestionView();
            } else {
                Intent intent = new Intent(QuestionActivity.this, ResultActivity.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b); //Put your score to your next Intent
                startActivity(intent);
            }
            break;

        case R.id.btnOptionB:
            if (currentWhyQ.getAnswer().equals(btnB.getText())) {
                score += 1;                }
            if (qid < 10) {
                currentWhyQ = whyQuesList.get(qid);
                setWhyQuestionView();

            } else {
                Intent intent = new Intent(QuestionActivity.this, ResultActivity.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b); //Put your score to your next Intent
                startActivity(intent);

            }
            break;

        case R.id.btnOptionC:
            if (currentWhyQ.getAnswer().equals(btnC.getText())) {
                score += 1;
            }

            if (qid < 10) {
                currentWhyQ = whyQuesList.get(qid);
                setWhyQuestionView();
            } else {
                Intent intent = new Intent(QuestionActivity.this, ResultActivity.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b); //Put your score to your next Intent
                startActivity(intent);

            }
            break;
        case R.id.btnOptionD:
            if (currentWhyQ.getAnswer().equals(btnD.getText())) {
                score += 1;                }
            if (qid < 10) {
                currentWhyQ = whyQuesList.get(qid);
                setWhyQuestionView();
            } else {
                Intent intent = new Intent(QuestionActivity.this, ResultActivity.class);
                Bundle b = new Bundle();
                b.putInt("score", score); //Your score
                intent.putExtras(b); //Put your score to your next Intent
                startActivity(intent);

            }
            break;

    }

}
public void setWhyQuestionView() {
    txtQuestion.setText(currentWhyQ.getQuestion());
    btnA.setText(currentWhyQ.getMultipleChoiceA());
    btnB.setText(currentWhyQ.getMultipleChoiceB());
    btnC.setText(currentWhyQ.getMultipleChoiceC());
    btnD.setText(currentWhyQ.getMultipleChoiceD());
    qid++;
}

}

Here is the results code:

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.result);
TextView t=(TextView)findViewById(R.id.txtViewResult);
Bundle b = getIntent().getExtras();
int value = b.getInt("score");

    t.setText("You answered: " + value + " out of 10! ");
    addListenerOnButton();
}

public void addListenerOnButton () {
    final Context context = this;
    button = (Button) findViewById(R.id.btnGo);

    button.setOnClickListener(new OnClickListener() {
        @Override
