"All science is either physics or stamp collecting". So said the great Ernest Rutherford and, true or not, this accurately reflects the view most physicists hold of their field.
Physics is indeed the most exact science with the greatest predictive power, apart from mathematics. Mathematics is also the basis of almost all physics. For the sake of your success if not your sanity, you should probably choose a different major if you're not willing to wade through mountains of complex math. It's also worth remembering that college-level mathematics isn't much like what you were taught in high school. Many problems require lateral thinking to solve instead of following a set procedure.
An undergraduate degree in physics is usually designed to provide students with a basic understanding of all its main fields: Newtonian dynamics, optics, quantum physics, thermodynamics, and more. Students generally specialize only at the postgraduate level, and may choose an interdisciplinary direction such as medical physics or quantum technology.
Many American universities advertise their physics programs by the number of famous physicists who work and teach there. When choosing a place to study at, though, you should keep in mind that well over a third of "American" Nobel prize winners in physics were actually immigrants. European universities definitely don't take a back seat when it comes to undergraduate education in this field.
