Pediatric Nurse Requirements High School Requirements For Nursing?

High school requirements for nursing? - pediatric nurse requirements

Finally, I decided to do a nurse (pediatric nurse actually) ... The only thing is ... I do not know what course to take for my final year at school. Am I obligated to take all the sciences? (Chemistry, biology, physics) and what kind of math do I need? Is there a need for processing power and advanced features? Requirements and needs of data management? plz help. Thanks
