My solution to the challenge!

//Setting the questions/answers arrays:
ques_ans=[["Who is teaching JS on Treehouse?", "dave mcfarland"],
          ["What tag is responsible for inserting JS into HTML file?", "<script></script>"],
          ["What's the name of Array of Arrays?", "two-dimentional array"]
          ]


//Setting a document print function and questions tracker:
function print_text(message) {
    document.write(message);
}

var counter_correct=0;
var counter_wrong=0;


//Starting the core program:

print_text("<h2>Please answer the pop up questions</h2>");
for (i=0; i<ques_ans.length; i++) {
    answer=prompt(ques_ans[i][0]);
    if (answer.toLowerCase()===ques_ans[i][1]) {
        counter_correct++;
        print_text("<ul><li>Good Job! that's correct<ul><li>That's "+counter_correct+" correct answer(s) out of 3 questions</li></ul></li></ul>");
    } else {
        counter_wrong++
        print_text("<ul><li>Oops! sorry, you got that wrong :(<ul><li>That's "+counter_wrong+" wrong answer(s) out of 3 questions</li></ul></li></ul>");
    }
}

print_text("<p>Your Results are: "+counter_correct+" correct answer(s), and "+counter_wrong+" wrong answer(s).");

if (counter_correct>counter_wrong) {
    print_text("<h3>You have successfully passed the test</h3>");
} else {
    print_text("<h3>You have failed the test. Click <a href=\"test_page_goes_here.html\">here</a> to undergo the test again</h3>");
}
