MCPHS-Boston: The first two years are "undergrad," the next four are "pharmacy school." If you applied there, you'd be applying as a transfer student and if accepted, would enter the third year, also known as the first professional (pharmacy school) year.
MCPHS-Worcester/Manchester: This is an accelerated, three-year program. All three years are considered "pharmacy school." You don't have to apply as a transfer student, you just apply, and if you're in, you're in. Most people who apply have a bachelor's degree or even a masters.
