I don't know hard facts about correlations between science and non-science grades, but I DO know there's a correlation between effort/ focus and science grades. I had no effort/ focus in my freshman science classes (or any, but luckily I could bs very well for history/ psych)
- I never had to study in high school, and never had my parents pushing me to study all the time to make them proud (boohoo for me? 😛), and consequently my first semester science grades are still haunting me (I'm retaking calculus now & I'm outta school, because I FINALLY developed some good studying habits that I didn't have my first year).
I was at early voting yesterday and ran into a girl who is a 1st year at my alma mater. We started some nostalgia about the good old hs days of no studying, and I revealed how on my first college test (chemistry) I was so proud of the fact that I had studies *3 whole hours* the night before (more than ever before)... only to discover I'd earned a c on the actual exam. Yeah, I wish I'd developed more focus/ better habits before starting my science tract that semester. Luckily things got better... I think?
So don't worry too much about correlations, and just set up a study plan, utilize office hours, and start studying way early for exams. I know, for me at least, there was a correlation between going to office hours with cogent questions and getting A's in my science classes... correspondingly, all my upper division sci profs got to know me VERY well. 😀
