<p>I know that the BC exam covers more topics than the AB exam, but on the free response section, four questions are the same out of six. I was under the impression that a lot of the mult. choice problems are the same between the two exams. But, with the Princeton Review book, I thought BC was much harder than AB. So I'm wondering if anyone has the released version of the 2003 exam and could tell me how many mult. choice questions the two exams have in common.</p>
