I majored in physics and chemistry (BSc 2014). When I started in 2011, I liked chemistry a lot and physics was mostly an afterthought, but in the three years I spent in that program, I came to like physics more and chemistry less. By my last year of college I was frequently reading about even more physics in my spare time, and also writing lots of answers about physics on Quora. You can find some of my answers mirrored here.
