+        This examination system has been developed with the intention of

+        </p>
+        <p>

+        <ul>
+        <li>For any programming questions, you can submit solutions as many
+        times as you want without a penalty. You may skip questions
+        and solve them later.</li>

+        shell or an editor to solve the problem and cut/paste the
+        solution to the web interface.
