<p>I am a junior self-studying Calculus AB for May exam. My local AP coordinator says I should consider taking Cal BC exam instead of Cal AB because I could get an AB subscore. I am not quite finished with Cal AB prep... </p>
<p>Q: Can I earn the same score on that 'AB subscore' as I would on just single AB exam? The AB questions on both AB and BC tests are identical? </p>
<p>There are questions on the BC exam that are identical to questions on the AB exam. Those questions are scored and an AB subscore is given for just those questions, along with your score on the BC exam. As far as getting credit for the subscore, it depends on what college you are going to attend.</p>
<p>^ Thank you. fyi, I really do not care about college credits because I have another year to go for Cal BC.</p>
<p>What makes me wonder after reading your answer is:
in case I take just AB exam, I get different set of questions than I do from AB part questions in BC exam?</p>
<p>Some of the questions are shared. But not all of them are, and the AB test will also have more of them (since it’s the same length but has no BC material).</p>
<p>You should get roughly the same score either way.</p>
<p>There are AB-style questions on the BC exam that do not appear on the AB exam. Only some of the multiple choice questions are shared, and while there are three common free-response questions to both exams, there’s a fourth question on the BC exam where part of it (commonly parts (a) and (b)) also contribute to the AB subscore.</p>
