I am just going to weigh in on biomed. You should think very long and hard before you decide to go down this road instead of choosing science.
Undoubtedly biomed is a better degree if you want to pursue a professional post grad health degree or reserach in the field of biomedical science.
That having been said, it is a complete pain in the ass and you will have to work your ass off from the very beginning and over 3 years (after having also done 2 years of VCE) this becomes very draining, especially when you can get to where you want with a science degree anyway. I am not going to go on a rant about how bad biomed can be, but basically there are some components of the course which have been very poorly thought out and are poorly taught. On top of this, you get virtually no freedom in choosing anything other than your major (which is limited to the biomedical sciences) and the odd subject here or there.
Finally, before you study biomed you should know about all of the compulsory cores that you are signing up for:
-Calculus (1 or 2)
-Statistics
-Physics for Biomed
-Chem for Biomed
-MCB (double credit points)
-HSF (double credit points)
-Molecule to Malady
-Frontiers in Biomed
First year subjects are pretty standard compared with science, but you are forced to take them all. Everyone particularly hates physics and stats, as they have no real point and are not prereqisites for second year.
MCB is a hard subject but doable provided you work hard.
HSF is a joke and the worst subject I have taken at the uni so far. I will be writing a review on this in a few weeks.
I've heard that M2M is similar to MCB in that it is hard work but doable.
Frontiers is the most whinged about subject in the whole degree. Probably the biggest joke subject out there, not that I have taken it yet.
Myself and many others regret choosing biomed over science on a daily basis.
Think is through very carefully. Don't get sucked in by the university's marketing juggernaut or pretentious douchebags who tell you to do it for the prestige. Make your own INFORMED decision because you will be a lot more comfortable with it.
There are several other reasons why I could tell you not to choose biomed, but I won't get into it here unless people really want me to.
