What is a reasonable curve for AP Stat?

<p>Hi, everyone. I am preparing for the AP Stat. I have heard that the harshest curve on one released exam is 75% for a 5. But the appass.com uses 63% for a 5. So what do your teachers tell you about the curve?</p>

<p>My teacher says 60-65% for a 5, the barrons AP stats says 63%, although it may be a bit higher/lower depending on the test difficulty. </p>
