>>8187961>>8187961Not OP, but BA in Chem from shit school, PhD in progress from top 5.
Get into research ASAP, it can potentially overcome a shit GPA (know someone who got into Caltech PhD with a 2.9 GPA, but was able to overcome it with amazing letters of recommendation and research), but keep your GPA high and try to find a lab that will let you take an independent project / a professor that will offer to be a mentor to you, don't be afraid to look in other departments too.
Chemistry is the "central science" as they say, and I was offered to do undergraduate research in the Chemical Engineering , Physics, Biomedical Sciences, Biomedical Engineering, and Chemistry departments.I chose Chemical Engineering because I liked what the kind of research he did.
I initially did research in the Chemistry department but had a falling out with the Professor but was able to get into another lab that I enjoyed much more because I had the necessary skills.
But pick something preferably something that you enjoy. Study hard and challenge yourself!
