Admissions and ap classes

Hi, I went to a British school that didn’t offer ap or honor classes then transferred to an American school junior year, I wasn’t able to take any ap because it required that you were a student for sophomore year, I feel like I’m at a great disadvantage because of this and I really want to go to NYU… But I haven’t taken any ap classes and they’ll assume I’m weak, would it be a good idea to mention this somehow in my college essay?
