What classes/course of actions should i start taking right now to become a pediatric nurse practitioner, or a registered pediatric nurse ASAP?

I am currently a sophomore, and I have already asked my counselors to allow to take an after school college credit Psychology class through SAC. I do not have a chemistry or a history; which bums me out bc i could've done AP world or chem honors. I am also in a magnet school arts program for instrumental music and trying to simultaneously take on CTE classes, such as Health Sci. Theory. Next year, ill be able to sign up for a CNA program at my school; furthermore, i also taking a medical assistant certificate for my senior year, which will allow me to log in for clinicals!!!! I am so excited to be as qualified as i can be. As of this beginning of the year, my lowest grade is a 97, and I wish to have as much college credit and honors to up my GPA and get noticed. Please, someone tell me what else i can do to stand out even more!!
