1. Depends what degree you did before pharmacy. Generally though, you'll start in first year as there will be pharmacy-specific subjects, e.g. professional practice, which obviously you can't take in any other degree. They're revamping the whole system so it may change but I still think you'll enter into the first year as apparently they're making the new first years cover some subjects that were second year under the old system, and basically just shoving everything forward anyway.
2. Yeah, what do you mean by "both courses have high demand" Bacilli?
3. No, you need STAT, and 50% uni marks/50% UAI. So your UAI shouldn't be too far behind if you want a stronger chance of getting in. It's generally a Distinction average that's required to transfer, so it is very competitive! And it's competitively based, so if you're unlucky and you get a WAM of 75 (exactly a Distinction) but everyone else above you got a higher average than you, then you might miss out. So aim as high as you can, and though Distinctions are fantastic, don't just aim for that 75.
4. Yeah, I'm not sure what's up with that, but I would presume so, so when you graduate you have 1 year of whatever degree + 4 years of pharmacy to pay off = 5 years. Best to check with the faculty.
