<p>To answer iamnervous, they use all of the AB questions on the BC test and weight them to be comparable to the AP test. BC is more holistic in nature.</p>
<p>sooo does ANYONE know what a four on BC usually is?</p>
<p>Yeah. Flip back to the first page of this thread and look at the McGraw Hill formula posted. It's pretty much roughly accurate.</p>
<p>iamnervous: you have to approximate the slope of the slope field (if I remember correctly, when x=0, y'=2, and when x=1, y'=-1.) so then you have the slope and the x and y value, do the euler.</p>
<p>The mcGraw hill one isn't very good.
There's a better one in the other thread.</p>
