This is the ranking of graduate students. Astrophysics and undergraduate theoretical physics are basically the same, and graduate students will highlight their own characteristics or high-end research.
Most of them are Ivy League, and Stanford and Massachusetts have made outstanding investments in undergraduate education. Princeton pays more attention to graduate students. If you want to learn basic physics, you can watch Leonard Su Shikan's lecture at Stanford, but you need a deep knowledge of calculus and linear algebra, and even you need to know the development history of mathematics and physics in the 20th century.
