Depends how you apply what I said. I meant it like: 'good understanding of principles will make 90% of the course significantly easier to understand.'.
Examples: group theory, stereochem, pretty much all main group chemistry (a lot of inorganic), crystal structures (a lot more of inorganic), etc... I could go on for a while. The main question is where in chemistry do principles not really help as much? Theoretical chemistry, quantum mechanics, statistical thermodynamics stand out for me. These (ST excluded) are the fundamentals of principles, so principles are really the answer to TC and QM.
