Hey Sunset!
Amazing results thus far - congratulations!
With rank 1, 100% on the exam would guarantee a 50. Getting 100% on the exam is
extremely unlikely, though. For context, the exam A+ cutoff last year was 159/200 (so, 79.5%). You can find those statistics
here.
With that out of the way, I'd try not to focus too much on the quantitative stuff. You've clearly done very well, so you
know how to get high marks. What I'd be focusing on at the moment is nailing each definition, really understanding links between different concepts in the course, and continuing on your merry way.
Re: the long answers. I feel that to the core, because your post above pretty much summarises my position word for word when I was in Year 12 haha. I also wrote too much, but hey, it worked! Things to consider, though:
* Make sure you give the best parts of your answers first (don't, like, try to finish strong or anything - just give the most obvious answers if necessary)
*
Make sure you practise in timed conditions - because it would suck to not finish the exam due to writing too much
Writing lots isn't a big issue on the assumption that you can finish the exam. Like I said, I was in a very similar position, so I made sure that I'd finish (and I
did finish the exam with approximately four seconds left lol).
P.S. For what it's worth, your SAC results are better than what mine were (but again, raw results don't really mean much), and I scored a 50 in HHD.
