You should take what most high school students consider a college prep curriculum. This will include composition/English, Sciences (probably Biology, Anatomy, Chemistry), and Math (at least Algebra and Geometry). Any college degree requires the completion of core curriculum which typically includes two English courses, math, science, etc. You typically complete these core courses before you move on to your major coursework. However, some programs build in your major courses during with those core courses. Your college nursing program will certainly include course heavy in Science - including anatomy and chemistry. And there will be "pre-requisite courses " such as taking Biology before you are allowed to take Anatomy (for example). You can look up college degree programs and the required courses for a specific degree online in college catalogs. You can also find recommended and required High school course work for specific degree programs on college websites or in college catalogs (online); look for admission requirements.
