<p>This is a question for current Tisch students. I'm a sophomore in high school, and my grades aren't terrible, but they're not great, either. NYU is one of my top schools, and I want to study acting or musical theater. I need to know if I need to work my ass off to bring my grades up for the next two and a half years. What were y'all's GPAs like? If I don't get a great grade in, say, science, will it make a huge difference in my acceptance, considering what I want to study?</p>
