Want To Get In USC

I’m a sophomore in high school and I currently have all A’s so far. I’ve taken a mix of AP, Honors, and regular classes. My ACT score will be at least a 30. I want to take automotive 3 next year, but it is a 2 period class, and we have 7 periods. I’m really interested in the class, but that would mean I’m only able to take AP us, math, english, science and study hall. I do not want this class to affect my chances. I am also on varsity XC and track. I am just not sure if this 2 hour automotive class will hurt my chances.
