What courses should I take in high school if I want to major in nursing?

Colleges do not expect you to specialize while in HS so you should take 3-4 years of Science including Chemistry/Biology/Physics (Anatomy/Physiology helpful), 4 years English, 4 years Math with Stats being helpful, 2-3 years of History and Social science (Psychology is a good elective) and 2-4 years of a Foreign Language. All these core classes will fulfill any requirements needed to get into a Nursing program.

It looks like you have a good schedule.
