I know, exam 1 was so tricky! =(
Exam 2 - lost marks on the same question as you. I think that question was screwed. Do you use Maths Quest - they specifically state that in the case of Integer solutions, you use the nearest 8 points to that particular point. I used 5, 4 to give $17000 but it's meant to be 2,7. I hate VCAA.
You'll definitely get a great mark! I still don't know exactly how much I lost on explanation questions, so like you, I'm hoping for the range 48-50.
Ya! Exam 1 was tricky, but you didn't trip up like I did! I guess it also comes down to luck too... whether you can pick up your stupid mistakes!

You're obviously more lucky than me! hehe.
Oh, I use Essentials, and I used MathsQuest for concepts I didn't get. My teacher taught us to find another point, but I didn't realise you couldn't have 4.5 and 5.5 flights (wasn't thinking straight - didn't think it was one of those cases where you had to consider whether it was realistic!), so I just left it, without realising it.
Yupo! I'd be happy with a 48+, despite what we discussed about personal satisfaction! (obviously be more happy with a 50. haha. but thats sorta out of the question now.

(btw, isn't it funny how we're talking about Further in a Methods thread? haha! sorry methods peeps!
