<p>OK so I'm self-studying and want to know how much of vector/polar equations show up on the test. In fact, I've seen vectors mentioned some places and not at all in others (test prep books I mean). How much of vectors is tested?</p>
<p>Also, I'm having conflicting stories from teachers and people like you guys on the difficulty of the test overall. My teachers say it's nothing like AB, that only a small portion of AB is tested. While this may be true (someone please give me some firsthand knowledge), I have seen on posts around here that even basic BC knowledge can earn a 5. What's more like the truth? </p>
<p>Thanks, I just want to make sure I'm making the right decision about self-studying. So far I'm finishing up on series and am concurrently previewing the polar/parametric/vector stuff that I will be doing more of during my spring break. Thanks!</p>
<p>You get an AB and a BC score when you take the BC exam, so you will need significantly more than just AB. I would say head over to apcentral.collegeboard.com and look at some past AP exams to check out the number of vectors related questions.</p>
<p>I was really good at series, which is supposedly really hard, but right now the polar/parametric and vector stuff is really killing me. I’ve heard there aren’t many questions on the AP exam pertaining to this particular topic so hopefully my incompetence won’t be my downfall.</p>
<p>The only thing that is hard about BC are the volume topics, I keep f—ing up the cross sections. It’s killing me! The series stuff are “okay”, the polar/vector/parametrics are only about how to use them, they never ask like “oh graph this r = r+rcos(x)” or something like that because that is pre-calculus (even though it was not in my pre-calculus…)</p>
<p>it’s most likely. However, there are chances that there will be a polar/parametric problem for the FR since 3 questions has to AB and 3 questions has to be BC.</p>
