Kilbaha 2012 exam 2

[xenial]

LOL yeah me. It took me 117 minutes, but I finished it with a 78/80

Would have been 80 if not for two very careless multiple choices -.-

In my defense, I forgot to keep my eye on the time; I checked the time at the start, after the MC section and at the end. I had no idea it took me 117 minutes until the end.

Emphasis on sane. Haha. Nah just kidding. Well done we expect great things from you. I can't really give myself a realistic score, I have a really bad habit of not taking practice exams seriously. But I just took off those 3 show that marks. I'm also a really slow worker - steady, but slow. Hopefully spec isn't too long this year!

I'm personally hoping they don't replicate 2011 levels of easy. To have an exam where 77/80 is needed for an A+...wtf.
Spesh exams should be difficult; it IS, after all, the highest level of maths VCE has to offer. Although they've declined in recent years and I don't expect that to stop.

Have any of you done KILBAHA 2013?

All my Spesh Practice Exams were above 85%. Feeling confident, I tried to do the Kilbaha 2013. Big mistake.

Ended up getting 66%

I think I got 77/80 for that one. Took me less time, but I was more careless this time ):

Whaaaat, I can't even begin to comprehend!
What course are you hoping to get into next year? (if you don't mind me asking )

That was actually quite annoying, the methods exam was harder than the spesh exam that year. Made absolutely stupid errors on spesh exam 1, which I still kick myself with to this day (yeah, it's just about the one thing in VCE that I can't let go of, everything else, meh ) It meant that weird GA marks gave weird study scores though, guessing because rather than a certain group doing really well on both exams, you had people doing really well on one and bad on the other and vice versa. Like, I got a B+ for exam 1 and A+ for the other two GA but still got above 40 (41), where as a friend of mine didn't do as well on exam 2, got A+ A+ A and got a 39. Was quite odd really. Guessing the B+ was high B+ and the A was a low A, with my exam 2 A+ being high.

In other words, wish for a hard exam

What?? Wait, so in 2011, what separated a 46 from a 50?

[xenial]

I'm hoping for an exam comparable to the methods difficulty last year! I found that fair, and it clearly separated people well - there were only 5 or 6 people in the state who got full marks on both.

Me? Science degree at Melbourne Uni

Yeah... the number of marks in each exam are worth the same amount, so a score of 74 and 159 would be miles better than a score of 80 and 135, for instance.

I want an exam where the questions are actually not all 100% completely accessible. They've been like that for the past few years. I did a VCAA exam once at 11.30 pm, after an entire day of music, in 61 minutes and only dropped three marks the first time through. That's quite pathetic I think.

What?? Wait, so in 2011, what separated a 46 from a 50?

Someone told me that around 2 marks separated 50 from 47.

Fair? It was soooooo short. I normally do exam 2s in 90 minutes; took me 70 minutes for that one. I dropped a mark still because I'm naturally careless and atrociously bad at spotting my own mistakes.

[ahat]

What happened that year that no-one got full marks in Methods (2008 I think)? Was there just no nliu's or..?

I found last year's methods too easy too. I finished in 69 haha bet you nliu 90 minutes

That was while there was still a separation between CAS and normal methods - only about of a quarter of the people did methods cas that year that did methods overall (I think).

Really? Omg you speed demons. I must've finished with 20 minutes to go. I guess I slowed right down to make sure I didn't make any mistakes though. Plenty of the people who got 40+ didn't finish - I think that indicates that it was pretty long for most people!

I am with you. I pray to the Almighty for an easy exam
My gosh, I can never forget this moment. 1 69 posts.
With my maturity, I am destined to ace all my subjects

Wait could you explain to me how they used the quadratic formula? Lol


And do Hefferman 2012 if you want a confidence booster

Let u=sqrt x
yu=16u^2-32
16u^2-yu-32=0
Comparing it to the basic quadratic formula where b=-y, a=16 and c=-32
u=(-b+-sqrt(b^2-4ac))/2a
but remembering that u>0 as it is the square root of x: positive square root branch
u=(y+sqrt(y^2+4*16*32)/32=(y+sqrt(y^2+2048))/32
u=sqr x=>x=u^2
Squaring yields (y+sqrt(y^2+2048))^2/1024
