Cambridge MML Advice for an American

Hi everyone, I'm sort of a lurker here and not used to posting so please bear with me.
I'm going into my senior year of high school (equivalent to Y13) at a US public school starting in September. Cambridge is my absolute top university choice, and I'm trying to decide between applying for linguistics or applying for MML (German & Russian). There does seem to be a "problem" / concern in terms of MML from an American perspective, though. It says on the Cambridge website that one of the languages you study you must have taken as an A-level, and that applicants should submit 2 pieces of marked work, one of which being in the language that they took at A-level. Americans obviously don't have A-levels, and what we tend to consider to be roughly equivalent would be AP exams (for reference, Cambridge considers 5 APs at a score of 5 to be the minimum requirement for all courses). My school doesn't offer German as an AP, but I did take the AP German exam (so I should be fine with regard to the having taken it at A-level side of things). Since I didn't have the option of taking the course, though, I don't have any written work that I can submit. Beyond that, it's not really standard at most American schools (mine included) for teachers to leave any real commentary on work, and if you ask they'll often say no.
It's also important to note that my school doesn't offer German even at a lower level, so there aren't any teachers that I could ask to go mark something even if I did have a piece of work to submit.
Would my inability to submit marked written work be something that could be accommodated / overlooked because it isn't really my fault so much as a problem with my school / the American system overall? Or would it disqualify me and therefore be better for me to apply for linguistics (which doesn't require written work and I'm basically equally enthusiastic about)?
Thanks in advance for any answers; I hope this wasn't too rambly.
