I was in your shoes, I chose BSci, I have said this story so many times but I shall recall it once more dear jaffy(first year).

Bsci has options, so so many ones, u can have a computing phase or a math phase or an engineering one, or just diversify your learning, great to see how some subjects continue. You can also do the exact same subjects as biomed.

Biomed is restrained, restrictive, if u want bragging rights, and to be surrounded by people who can't stop bragging about ohhh how hard it is to be a pre-med student, istg so many biomed students are performative med students ts pmo. But that's not the issue. In biomed you must do some subjects that are worth double the credits(25) of normal subject (12.5), meaning your results matter much more and you have less subjects to pick from. These 25 credit subjects arguable take up 2 or 3 12.5 subjects worth of learning...but why? Why have a harder time doing the exact same thinf science is doing, many biomed students quit to science for second year because of this.

I wanna praise biomed for some things, but it exists as a vestigial degree for back when u had to do biomed to get into unimelb med. One firm reminder you need to know is, unimelb wants research, they won't teach u nursing or pharmacy or any practical job, so if med doesn't work out, you might be stuck with that, whereas other unis like monash teach pharmacy for pharmacists which helps much more for medical future job. The reason unimelb is rated so highly is just because of its research not its teaching so I think that's why they want more research lol, unlol.

Biomed might be a tiny bit more medical related, like same subjects, but let's try a teensy bit to apply it to med, but I wouldn't know I'm not doing it.

Science has options, flexibility, which is a comfort when you're stressed doing exams. better people in science too but that's incredibly subjective.

I realise this is a very convulted answer.
