 <h2>Help/FAQ</h2>
 <h3>What is this?</h3>
@@ -18,14 +18,14 @@ <h3>I don't agree with an answer!</h3>
 <h3>How does scoring work?</h3>
 <p>If you are taking a fixed quiz (not just answering random questions in training mode), you get one point per correct answer. If you used a hint for that question, 0.5 is subtracted from your point. For each incorrect attempt you made at that question, the point is further divided by two. For instance, if you used one hint and three incorrect attempts, you get (1 - <abbr title="You used a hint and loose 0.5 points">0.5</abbr>) / (<abbr title="You used three incorrect attempts, so divide by two thrice">2 * 2 * 2</abbr>) = 0.0625 points. As you can see, it pays to think things through rather than guessing, and using a hint is often also better than guessing.</p>
