<p>A couple of things about the AB/BC piece:</p>
<p>32 of the 54 FR points are used for the AB subscore, as are 26 of the 45 MC questions. The 26 MC questions are multiplied by a constant that is slightly higher than 1.2, so that the total AB subscore is out of 64 points.</p>
<p>The curve isn't made big by the mathematical intelligence of the people taking the exam. The people who score a certain percentage of key multiple choice carryover questions will earn score's of 1's, 2's, 3's, 4's, and 5's, in approximately the same percentages of the group with that score, regardless of the actual SIZE of that group.</p>
<p>This has to make sense. Suppose that everybody nationwide could be actually convinced to earn no points on the AP Calculus exam. One student, in order to have a little fun, answers a question in a way they think is incorrect, but accidently earns 1 point. Do we really think this student is earning a 5?</p>
<p>And while christalena2's point regarding each question being worth more increases the chance of getting a lower percentage has some truth to it, each question that is correct increases the chance of getting a higher percentage, too, so to speak. What's really happening is that when you take the BC test, every AB question has significantly more weight to it.</p>
<p>If you take a 100 question test, you have a chance to miss more questions and still earn an A, but that test is going to delve more into some of the minutiae, and the chances that you might miss a question should probably increase.</p>
<p>If you take a 50 question test, you have fewer questions that you can miss to get an A, but that test probably isn't going to hit quite as much of the minutiae, and so the chances that you might miss a question should probably decrease.</p>
<p>This, of course, presumes that you have adequate knowledge of the course material.</p>
<p>As to the real question of, "Should I take AB or BC?":</p>
<p>It really depends on the culture of your school. Some schools offer BC only as a course that you take after AB. This doesn't sound like the case in the OP's school.</p>
<p>While the grades in Honors PreCalc sound sufficient to take the BC course, it worries me that the recommendation is that only Honors Analysis students take the BC course. (And why are there two courses labeled Honors? Sounds like overly liberal use of the word "Honors" to me.) It also worries me that you didn't "know" about the Honors Analysis course for some reason.</p>
<p>I would find out the difference between the two courses of Honors Precalculus and Honors Analysis. It may be that the Honors Analysis course has already started through the AP Calculus BC curriculum set (it's one way some schools get through the BC curriculum in one year, without stressing their students as much). Is it material that your Honors Precalculus class has covered? Could you cover it independently, and as well as your AP Calculus BC instructor would require?</p>
<p>I think you need the answers to some of these questions before you answer the question of what course you should take.</p>
<p>As far as taking AB in one year vs. taking BC in one year, you're covering approximately 15-25% more in BC, without much added depth, depending on how rigorous your high school precalculus program is. So the battle that you might be fighting in BC is the pacing (that's what kills the majority of the BC kids at my school).</p>
