<p>which was experimental and what were some of the questions in the experimental</p>
<p>It’s hard to ascertain which section is experimental – the only way you can tell is by noting that there are a certain # of graded questions, including 10 grid-in questions. For example, if you see two sections that both contain grid-ins, then one of them is experimental.</p>
<p>The online score reports tell you which questions you missed, etc. so you can tell which one is experimental upon receiving your results.</p>
<p>Was the section with 9t^2-r^2=17 20 minutes or 25 minutes?</p>
<p>I believe that was 25 minutes.</p>
