Oxford Requirement Confusion

Hi, US student here! So i’ve decided to apply to Oxford with my intended major being Economics & Management, however, I was confused about the meaning of the requirements. It would be helpful if anyone knew the US equivalents the requirements list stated on their website. (I understand some parts such as AA/AAB, but confused about the A*AA including mathematics. Does this part mean I must have gotten a 5 on the Calc BC exam?)

(This is what is listed on the website)

A-levels: A*AA including Mathematics at grade A or above

Advanced Highers: AA/AAB

IB: 39 (including core points) with 766 at HL

Or any other equivalent (see other UK qualifications, and international qualifications)

Yes, BC calc with a 5 (achieved or predicted). If it is a predicted mark, any offer you get will be ‘conditional’ on achieving the 5 in May/July, so you will want to have a back up plan.
