Based on my limited knowledge, I believe the new curriculum was designed to combine different components into one big course so that students can learn and relate material more easily. For example, BMS116 (Bio Medical Science) has three different components (Anatomy, Histology and Pathology). Instead of learning them separately, you learn them at the same time. IMO, it's better that way.
Regarding the board exam, I think most students use UCSF material as a👎 reference/additional material. It's like we prepared for the DAT. Most of us use some sort of prep material in the market. If one wants to score higher, he/she would use their old notes or other prep material.
Regarding the dean, I always find his speeches interesting. There's always something in his speech to think about or carry with you. Maybe it's just me.
