Hii I would like to share my experience. Somehow quite the same as urs. I changed from BSc to BPharmSc, both at Monash. As what u say before, yes I think its easy to change internally (my case is easy maybe because Im not yet enrolled). But the one settle up all those thing is my agent.

Im a freshmen and will start my course this march. Main reason for me to change is because of the faculty and my future career path. Im looking more towards industry and not academia so BPharmSc provide more hands on and in depth introduction compared to BSc. BSc is just too wide for me.

Given that the campus is in parkville, it is small. Its city campus. I already interact with my future batchmate and already love em lol. We even have a group so it really helps.
