<p>^And yet, for AP Calculus AB, in the last 10 years the percent of 5’s has risen from about 18% to about 22% while the percent of 1’s has doubled from about 17% to about 33%.</p>
<p>Since the number of people taking the test has doubled in the last 10 years, the number of people getting 1’s has quadrupled.</p>
<p>The percent getting 3’s or higher has gone from 65% to about 55% in the same time frame.</p>
<p>So, i suppose it depends on what AP course you are talking about.</p>
