I'm currently a chemistry major at a community college. I'll be transferring next fall to a UC here in California (Davis or Berkeley). I still love chemistry, but now I'm wondering if my true interest would be best served by studying physics instead. My interest mainly lies in atomic/nuclear Chem/physics and I would like to get a PhD in the future, do research. Honestly I'd like to major in both, but I worry that my grades would suffer. I guess I'm just wondering if anyone has done it before and the feasibility of majoring in both while maintaining good grades or whether it's a waste of time.
