The electives bit is not something i'm over familiar with. In first year some modules were decided on the basis of previous experience. ( If you didn't do A level maths/physcis/biology, you did foundation bits in those subjects).
Other than that the only choice we got was in final year, where you get to choose what area of pharmacy you'd prefer to do project/essay in. You also got to choose 1 subject in each semester of 4th year, but not a huge amount of choice overall thoguh.
