P2 is relatively harder in a sense that you have much more materials to be absorbed in a same period of time comparing to P-1. However, the materials are more interesting because you actually learn about the disease state management and clinical approach to improve patients' outcome as a pharmacist. In P-1, you might learn about this drug A, mechanism of action this and that, adverse side effect,....take the test....then forget the next day and don't even know why the heck you have to cram a bunch of drugs together for. In P-2, you learn about the disease first, their pathophysiology, symtoms, and then learning about the drugs that treat/prevent such disease with specific population (elderly, adults, kid, kidney disease patients, asthma, etc....)
I enjoyed both years. But P-2 is when i really get my appreciation about the pharmacy profession. Good luck...and study wisely.
