<p>Thanks for the explanation, it helped when i re-visited the topic.</p>
<p>Are the AP Calc AB tests from 1969-1998 pretty accurate to the modern tests, or are they harder/easier? Also are some topics on the 1969-1998 tests that are not on recent tests?
One more question, are the Princeton Review Questions good practice for the real exam, and is the practice test from Princeton Review similar to the real thing.</p>
<p>1998 should be relatively accurate, although slope fields has been added.</p>
<p>Other topics have been taken off, such as partial fractions (which I'm not sure if it was on there or not in earlier years), integration by parts, and the strength of the emphasis on precalculus topics.</p>
<p>The current tests tend to be more conceptual and less computational, although in 2007, the stronger computational ability has crept back in a little.</p>
<p>I'm not familiar with the Princeton Review questions, and can't speak to the quality one way or the other.</p>
<p>I don't have any practice book recommendations. With my students, I exclusively give the older tests. I don't give anything before 1985, though.</p>
<p>I finally got through all of the material today .. so now it's time to practice, but I noticed that there was very little differntial equations coming on the test.
Is homogeneous differntial equations test on calc ab?</p>
<p>I don't think homogeneous differential equations are tested. Generally you only need to know how to solve separable differential equations (which mostly involve exponentials). However, I think I may have seen one or two logistic differential equations back when we were given old Calc AB FR's to do (I know they are on the BC exam).</p>
<p>Slope Field problems have traditionally had nothing to do with Euler's method.</p>
<p>You might be asked to approximate a value using a tangent line (basically a first order Euler's method problem), but if you understand tangent lines, you don't need to know Euler's method to find it.</p>
