One minute? Hm. One side note then: nobody needs the "knowledge" tested using such kind of tests? What, are you training monkeys?

[EDIT]
In case somebody did not understand it: testing based on choice of variants is the way to "educate" students into idiots; some are already "educated". I don't care this is a "requirement": people who killed prisoners in concentration camps also did to meet the "requirements". Education system based on such tests is a kind of concentration camps and genocide. Now, down-vote as much as you want.

A comment to the one who just voted 1 for this answer: now you can see the result of it: a monkey gets offended when it's called a monkey and down-vote humans.

*grin* that much is probably true, but online exam systems are common all the same, and a common homework task. The bigger issue is, if he only impliments it on the client as shown, it's trivial to hack. BTW, I'd 5 you, but I can't vote on CP as I don't want to give them a working email address.

This is a small mockup utilizing javascript to manage the time out. When realizing this project I'd use jQuery for extended javascript functionality and ease of use. Nevertheless as a simple proof of concept it suffices:

XML

<html>
<head>
    <script type="text/javascript">
        function hideQuestions()
        {
            // Hide the questions
            document.getElementById("answerBlock").style.display = "none";
            // Show the message that the questions timed out
            document.getElementById("quicker").style.display = "block";
        }

        function checkTime()
        {
            secondsLeft = secondsLeft - 1;
            if(secondsLeft <= 0)
            {
                hideQuestions();
                //alert("Time is up!");
                document.getElementById("secondsLeft").style.color = "red";
                window.clearInterval(myTimer);
                writeTime("Timed out!");
                // Here you'd probably want to do a redirect to another page
            }
            else
            {
                writeTime(secondsLeft + "s");
            }
        }

        function writeTime(msg)
        {
            document.getElementById("secondsLeft").innerHTML = msg;
        }
    </script>
</head>
<body onload="">
<h1>Timeout Exam Question: <span id="secondsLeft"></span></h1>
<div id="answerBlock">
<input id="answer1" name="answer1" type="text" /><br/>
<input id="answer2" name="answer1" type="text" /><br/>
<input id="answer3" name="answer1" type="text" /><br/>
<input id="answer4" name="answer1" type="text" /><br/>
<input type="button" name="submit" value="Answer Questions"/>
</div>
<div id="quicker" style="display:none;">
You must answer more quickly next time!
</div>
</body>
<script>
    var secondsLeft = 10;
    writeTime(secondsLeft + "s");
    var myTimer = window.setInterval(checkTime, 1000);
</script>
</html>
