Look mate you're in yr 10. The fact that your name is 'futuremedstudent' is somehow giving me the idea that you really want to get into medicine. That's fine I guess, but seeing as you're in yr 10 there's some hard truths you should face now so you don't get bitterly disappointed later down the track. Don't invest too much time and emotion solely into the prospect of getting into medicine. Yes you should be aiming for the best results you can possible get, but like square said, you've gotta be realistic. With the admission rate into med programs being something like 3-5% (engineering is like 85% for reference) and every tom, dick and harry trying to get in, things are looking statistically bleak. There's guaranteed to be a whole bunch of talented and bright kids that genuinely put their best efforts into getting in, but don't. Yet everyone thinks they're the statistical exception.
Anyway what I'm saying is that if you latch onto, and commit to, this idea of medicine so early you're gonna be so much more disheartened if you don't make it through. I'm not trying to be rude, but a lot of students in yr 10 will generally lack the maturity to full comprehend what a career in medicine actually entails. Check out many of the posts made by Medman if you don't believe me. Don't get suckered into this idea of medicine cos of the prestige, of being able to call yourself "Dr" and impressing people, and because of wanting to make your Asian dad proud. This is the part where you tell me that's not the reason why you want to go into medicine, something something helping people.
Believe me I've been through all this crap. Top of all my classes for years, people have been telling me I should become a doctor, this that. Been studying for the UMAT since December last year, week in week out and what do I have to show for it? 50th percentiles and a raw mark that never changes.
Ask yourself why you want to do this - and not just superficially. You have over 2 years to fully think it through. My best advice to you now would mostly be to CHILL THE HELL OUT (I saw in another thread you study for 10 hours a day? I'm sorry but in yr 10 that's not commendable that's mentally ill). I'm telling you that because I'm sure you're going to get fantastic results and kill it - but are you the 4%, or will you ever be the 4% for that matter?
