Is it worthwhile to take the AP Calculus BC if you are not studying in the AP/American curriculum?

Hi, I'm studying the CBSE curriculum in India, and I'm giving AP Calculus BC next year. I am applying to US universities this fall, the problem is that I don't have scores in my hand at the time of applying so I have just reported the expected date of taking exam. A single AP exam in my country cost Rs 9500 ~ $158, so would it be worth shelling this amount? I have already prepared for this test. I know I can take this for credits but would it still enhance my application as I do not have my scores.
