At the moment, I am a physics major and also putting a lot of emphasis on math. I am in my second year of undergrad at the moment. While my "dream" goal does include going into a PhD for physics, I do realize it's a long and demanding journey, so I have also been looking at actuary related jobs. If I were to go into actuary, I know I will also have to focus on economics and/or finances along with the math I am doing at the moment, but I am not entirely sure what specifically. Are there any good sources for this or anyone who can tell me what steps I should take to make the goal slightly more feasible?
