Just a slightly off topic question:
Approximately how much time do you get for yourself/family/friends, etc as a med student/fully educated doctor?
As a doctor, certainly later down the line during registrar exams, studying becomes a large part of your non-working life. But otherwise, from all accounts, it's possible to maintain a healthier balance if you really want to. Certain hospitals are said to work their junior staff harder than others, but even then, a balance is possible. Granted, Russ is probably better equipped to answer that one.
As a student, other than maybe SWOTVAC, a balance should definitely be achievable. It's also important to remember that in uni you study as much or as little as you want, and in the end of the day pretty much everyone (or rather, every domestic student) who passes becomes a doctor anyway. You don't need to strive for a big 80+ any more like many would if they were going to try and get in to a graduate-entry course. Your med school marks become significantly LESS important as you move up the ladder; just like VTAC didn't ask you for your NAPLAN results, the various Colleges don't care much about your med school marks.
