WOW That website was amazingly great! 3x Better than I thought it will :smiley:

According to me these are the slight changes that must be made to your program.

function print(message) {
  document.write(message);
}
var questions_Answers = [
[prompt('How many states are in the united states?'), '50'],
[prompt('What is the color of the sky?'), 'blue'],
[prompt("What's the color of apple?"), 'red']
];
var counter=0;
function printResult (questions) {
var correctAnswers='<h2>Questions that you got correct</h2><ol>';
var wrongAnswers='<h2>Questions that you got wrong</h2><ol>';
for (var i=0; i < questions.length; i+=1) {
if (questions[i][0]===questions[i][1]) {
 correctAnswers+= '<li> You got question number ' + [i+1] + ' correct! The answer is '+ questions[i][1] + '</li>';
  counter +=1;
} else {
  wrongAnswers+='<li> You got question number ' + [i+1] + ' wrong. The answer is '+ questions[i][1] + '</li>';
  }
}
correctAnswers+='</ol>';
wrongAnswers+='</ol>';
print('<p>You got a total of ' + counter + ' correct answer/s out of ' + questions.length + 
    ' questions.</p>');
print(correctAnswers);
print(wrongAnswers);
}
printResult(questions_Answers);
