answer:Are you just talking about performing well in school, or making a career in these fields? If the former, some research has shown that grades in all three subjects are correlated with time spent doing homework. And listening to your teacher. (Okay, I might have made that one up.) Basic algebra will be useful to you in all three classes; math through calculus could be necessary for physics depending on what level you take. (I slid through college with algebra-based physics and never looked back.) If you’re talking about careers, being analytical, creative, and a glutton for punishment will be critical.
