The issue with chemistry is that you need to develop a "feel" (chemical intuition) for a lot of topics. A lot of chemistry taught in undergrad, like Organic, cannot always be neatly explained or solved with an equation. On top of that there seems to be as many exceptions to rules as there are rules themselves.
Exactly what I was thinking at that time. My conclusion was that they were forcing me to admit tons of things while at the same time confusing what could be understood logically and what had to be accepted as is.
Physics and math also lean heavily on intuition; you might have a clear cut path through the equations when you have the solution in front of you, but there's often no "playbook" that you can follow mechanically to get what you want from the fundamental equations.
