What are the most important chemistry subjects to learn as an undergrad and grad student? Physical chemistry isn't required for my (engineering) degree but I'm considering taking it so I can do a ChemE Master's. Any warnings or praises for it? Otherwise it's been:
>gen chem
>organic chem
>biochem
And honestly, haven't been as impressed by gen or biochem as I'd have hoped. OChem was fun and I've found some important practice and information through biochem but both suffer from too broad of content in too little time.
