Some of the text below may come across as though I'm blowing my own trumpet but I think that I need to explain my situation to help OP.
Let me tell you a little bit about myself.
When I was a young child, everyone thought I was very intelligent. People would always praise me to my parents about how courteous, respectful, mature and intelligent I was. My parents got me started on learning quite early too so I guess lots of that helped. I cruised through primary school, consistently at the top of my class, still collecting much praise with no difficulty.
Once I hit high school, things started to take a turn for the worse though. Since I was at an elite private school, this was picked up on really quickly (especially given my past track record) and my parents were contacted immediately etc. Nothing really bad happened at all, I just became disinterested in studying hard any more. I really didn't see the point of it and preferred to spend my time playing music (classical guitar and piano), gaming and hanging out with friends.
My parents kept trying to "talk some sense" into me but to no avail. I was just lethargic.
My moment of sudden clarity and realisation was more of a dripping faucet at the back of my mind that increased in pressure over a long period of time during the middle of year 9 towards the start of year 10. I started thinking about what I wanted to do in life and what I wanted to achieve. Constantly slacking off and enjoying life "today" simply was not going to cut it.
I was fortunate enough to live a privileged life and this started playing into my thoughts too (as selfish and taboo as this sounds). I always knew that I would go to university but it was at that point that I decided that it had to be something good. I didn't want to go to university just for the sake of being able to say that I go or get some dead-end job that will take me nowhere in life.
That's when I decided that it was my goal to achieve an ATAR score of 99.95. People laughed at me, people mocked me, people ridiculed me and blatantly told me that I would never achieve that score. In the end they were right, I got an ATAR of 99.85.
In VCE I didn't really think too much about courses or university or anything. I just picked subjects that interested me and that I thought I would do well in.
I must say, I had a huge preconception about what VCE would be liked based on anecdotes from those around me. Long, sleep-less nights, tears, boredom, cramming like a mad hatter for exams..
But now that I look back at the whole experience, cool, calm and collected, it was nothing like that. I never really focussed on the big picture and didn't worry about anything while I was studying. I just focussed intently on the task at hand and ensured that I fully understood the intricacies and nuances of that concept in great detail. I didn't study excessive hours, still managed to hang out with friends every week and even managed to make it to the gym a few times a week.
With all of that said, I thoroughly enjoyed my subjects and pushed myself to study and study effectively during study hours so that I could enjoy other activities later. All of this made my parents very proud, also.
When the time came to put in my VTAC applications, I was perplexed. I always enjoyed quantitative subjects and really enjoyed accounting (it was also my highest raw study score) so I decided that I wanted to study a Bachelor of Commerce at The University of Melbourne.
My parents always had dreams of me becoming a doctor and despite my non-existent desire to go into medicine, I decided that I would apply to James Cook University for a place (I didn't sit the UMAT and JCU doesn't require the UMAT). I did end up getting in but I didn't accept the offer.
I'm currently studying the BCom program at the UoM and I couldn't be happier. I employed the same study skills and habits I developed in VCE (although I studied a lot less) in semester 1 and I ended up doing okay.
So that's my story there for you.
All I can say is that do what you enjoy. Evaluate your priorities and set one or more goals. Work towards that and hopefully you'll get there.
Best of luck,
Gekko.
