 <p align="center"><strong>Time limit</strong></p>
 
-<p>With time limit you can control how much time student can have
-on one quiz attempt. If time limit is exeeded, the quiz will be sent
-automatically, with current answers. If student backs down and returns
-to quiz attempt when time limit has expired, zero grade will be marked.</p>
+<p>By default, quizzes do not have a time limit, which allows 
+   students as much time as they need to complete the quiz.
 
-<p>Zero value means, no time limit.</p>

+<p>If you do specify a time limit, the several things are done to try and
+   ensure that quizzes are completed within that time:</p>
+
+<ul>
+  <li>Javascript support in the brower becomes mandatory - this allows
+      the timer to work correctly.</li>
+  <li>A floating timer window is shown with a countdown</li>
+  <li>When the timer has run out, the quiz is submitted automatically
+      with whatever answers have been filled in so far</li>
+  <li>If a student manages to cheat and spends more than 60 seconds
+      over the allotted time then the quiz is automatically graded zero</li>
+</ul>
