The reason why I wasn't thinking of staying there is because like most people that study med science, I wanted to (by the end) apply for medical school and I would rather get med degree from usyd or unsw than uws...
If your doing Med Sci as just a means to do postgraduate medicine.. I would recommend staying at UWS.
It's easier to obtain a higher GPA at UWS then at USYD or UNSW.. and in the end entry into postgraduate medical schools is based on GPA+GAMSAT+Interview. Postgraduate medical schools don't consider where you did your undergraduate course, only your performance in that course.
Furthermore you really shouldn't have an attitude of "I would rather get med degree from usyd or unsw than uws..."
USYD is a postgraduate medical school.
UNSW and UWS are undergraduate medical schools.
They each have different requirements.. and if you are considering UWS med science - and not Adv Med Sci.. then I'm assuming that your ATAR is <90. If so, UNSW is immediately an impossible medical school to obtain, as you must have a minimum ATAR of 96 or 92 (if you obtain a 7.0 GPA).
At the end of the day, Medicine is Medicine.. and UWS Medicine is a very well-recognised degree.
