<p>So how do you figure out which section was the experimental?</p>
<p>In principle, you can only narrow it down to one of two sections. For example, suppose that you had two 20-question math sections; in this case, one of those is the equating section. However, other people will have a different equating section but only one 20-question math section. The extra math section you had which doesn’t match theirs will be the equating section.</p>
