<p>Exactly. In fact chem and physics majors spend a lot of time studying the exact same science and math. Group theory is group theory no matter what your major is. </p>
<p>OP, any major can be difficult. What determines outcomes is passion for what you are doing. If your passion is physics, then it might just be easy for you. My passion is chemistry, and I am doing very well. Physics is not inherently more difficult than chemistry. When I started college, I was a dual degree student (music, chemistry). I found music theory much more difficult than chemistry, math or physics.</p>
