To pursue a major in physics, establishing a strong mathematical foundation is crucial. Key areas of mathematics include calculus (Calc 1, 2, and 3), ordinary and partial differential equations, and linear algebra, which are essential for success in undergraduate physics courses. Many colleges provide recommended course sequences and textbook lists for aspiring physics majors. Engaging with physics communities, such as forums, can help fill knowledge gaps and provide guidance. As a senior in high school with limited physics experience, it's important to build on your current understanding and explore both the philosophical and mathematical aspects of physics to deepen your interest and knowledge in the field.
