What to fill in 'Year of high school graduation or equivalent' on ACT registration form?

In India high school is 9th and 10th while in US, they consider high school in from 9th to 12th. I am in 12th presently and according to India, I completed my high school in 2013 and according to US, I am still in high school and will complete it on 2015. Please reply urgently.

2015, and not 2013.
