I didn't find the paper terribly hard, It was challenging but manageable. Saying that however, I found myself taking way too long doing the multiple choice questions (about 45+ minutes) with the 25 questions(bit strange, I was expecting 20). Halfway through the test I kept staring at the clock worried that I'd run out of time. Finished in the last five minutes, so not too bad. I can't help but think about questions I probably answered wrong though. Glad general maths is now done. Now just got to focus on the last few exams

hahahha what?
i think you're talking about the wrong question
i agreed to
C = 120000/n
oh strange.

i got 3/8 too, how do you know your right?
dont worry. im right. the few points that u lost isnt a big deal.

I got 3/8... which is right...?
nope 2/9 is right no doubts.

HAHA felt the exact same thing... especially when looking at that triangle question and they want degrees and angles and lengths and proving 114 and all I know is a2+b2=c2

That was waaay easier than I expected, heaps better than trials! But that's only cos trials were completely fucked and this kind of made sense. Multiple choice took me a while to finish tho, finished early and felt alright about it but you never know with maths but who cares #HSCYALATER!

Time zones are based around longitude not latitude
shit! what was the answer for that one? afraid i might got that wrong...

Did you do 140 mins?

If you did 140mins will probably be 1 mark out of the 2 since you did the degrees x4 = time difference.

Also, for the financial probability expectation crap the answer was \$2..? But the answers which were published say it is \$0 no loss or win....???????

Yes, I got \$0 for that, most people forget to take away the payment fee to actually play the game.

I don't think you will get any marks because not only is it not right but you've used latitude not longitude. Latitude has absolutely nothing to do with the time difference

i forgot, what was their difference in longitude? anyone remember?

i think i got 2hr something in my answer but i don't think i calculated something related to 140 degrees 0_0 what was the right answer?

Yeh it's stupid. I only know because I had to get insurance when I got my P's. Otherwise I'd have no clue.... Did anyone else catch the trick btw with the bicycle/bus is cheap?
It's 2L, 34km ONE WAY, she then has to go back home another 2L,30km so the bicycle was like \$30.40 cheaper
But the bus ticket was \$36 (Not sure of the exact number) for 10 one way trips. In the end, it was like 20cents or 30cents cheaper per trip for a bike.

was the time difference question like 11 hours or something?

nop i got 2 hour 40 mins around there. You use the longitude (second number) in which the difference wasn't that big.

just divide the difference by 15 and change it to minutes/seconds and you got 2 hour something

"Sydney, Australia is 3 hours ahead of Singapore" - googled it so i got around that.

yup i got \$0.30.

The bus was the amount 10 single trips (so 5 paired trips) so you just multiply 34 (motocycle trip) by 10 and you get 340 km, divide 340km by amount 17km and multiply it by 1.67 and you get it is 30c cheaper than 36.40\$ by bus.
