<p>Memorization is not as key in ES as it is in other APs; rather, it focuses also on a development of logic regarding the environment, so there’s a substantial number of cause and effect style questions and so forth. But good memorization is always a plus, and it’ll help her substantially in these last few hours.</p>
<p>I’d say she sounds like she can manage a four. I wouldn’t necessarily recommend an all-nighter unless she’s well rested now (man, I sound old…), but as much studying as possible is always a plus.</p>
<p>I’m guessing the cut-off would be around 50%, maybe a little higher.</p>
<p>30% get a one because they either are forced to take the test by their schools, or are trying to get out of taking a final (the policy my school has). Since the majority of students taking the test hear that it is very, very easy, they tend not to study much, if at all for it, resulting in a lot of bad scores. Furthermore, in my experience, a lot of the students taking the test really aren’t quite ready for any kind of AP test.</p>
<p>I’m glad to have been of help! =)</p>
