Math placement test???

I am taking Calculus AB and BC and have already taken the AP exam for it, however, I am worried that when I take the college placement test (I am REALLY bad at standardized testing) somehow I will end up being bumped down to Pre-calculus or something. Which would really suck considering I've taken a calculus 2 course.... Is there any way to express this to the college if the above situation were to occur? My grades in the cl is great, and if I don't get a high enough score on the AP exam and end up having to take the math placement test.. and please don't say something like "if you know the material youll do fine" its not the case with me, i know the material and the curriculum and do well in the cl i just have a hard time on standardized tests! help..
