Can IB help me get into an art school?

I am an international student interested in studying in an american art school. My current high school offers the IB diploma program, but they don’t offer any IB art classes. I don’t know how, but they’ve managed to substitute IB art classes with IB foreign language classes. Do you think I should do the IB diploma program or should I spend this time taking extracurricular classes and making a portfolio?

Thank you!
