In the U.S. you can do 2 years pre pharmacy course work. Then most pharm D programs are 4 years. I believe there are a couple of schools that are 3 years. When I applied (2000) I was accepted first try. I had a pretty good PCAT score and good GPA (they focus on science grades). Every year after, the incoming applications to the program seemed to at least double. Therefore, it got progressively harder to be accepted with all that competition. That being said, I've seen a wide spectrum of people graduate pharmacy school. From "damn they're smart" to "they're a moron". As long as you pass the classes and boards they give you a license. Common sense isn't something that can be taught. As far as nuclear pharmacy, you don't need to do a residency. You can basically apply for the position and usually most places will give you training (sterile compounding etc) a lot of which you get a little experience in pharmacy school. The only thing about nuclear pharmacy is the hours aren't really attractive.

What country are you in?

In the US, you do 2-4 yrs of undergrad, then spend about 4 yrs in pharmacy school. If you want to do Nuclear Pharmacy, I'd imagine you'd have to do a 1 yr residency specializing in it but I'm not too positive on that.

You have to be decently bright. Hard work is a lot of it too as you have to memorize and understand so much. It's hard to quantify how "bright" someone is though.
