It all is foundational. Your secondary school education merely teaches you to think critically and prepares you for higher education curriculum. It is non-specific to fields of study.

College builds upon those core skills learned in high school and then moves the student to higher level thinking. It is designed to prepare people to be able to problem solve and do critical thinking that will enable them to manage in the real world. It is also designed to prepare people for specialty areas of study.

Take your time. You have plenty of time to decide what you want to be when you grow up.
