One of the harder papers in the last few years IMO. ~85/100 raw I think. (Perhaps subtract some silly mistakes from below)
If I had to estimate....

10/10 MC

Anybody care to guess B6 raw cutoff?

I got a = 4.5.

 

[fruitcandy]

what would the b6 cut off be?
80?

 

[blinx96]

Fuark.. I won't even pass if that's true

well in 2011, someone who got a raw mark of 99/120 (or 82.5%) was given 89 as their exam mark.
So if this years paper was harder than the 2011 paper, then yeh i guess 82 is approximately right

 

[ocatal]

my guess... 82

Considering last years cut off was 83 and the exam was considerably easier, I highly doubt the cut off for this exam will be 82.

Agree. I feel like a 78 would cut it ...

 

[avhead]

I got a = 4.5.

Can you explain how you got to that? (Mind you, I took a complete guess)

 

[blinx96]

do u reckon it will be lower and higher (like i mean which exam was considerably easier lol) ? (and I'm just saying 82 so that people don't get false hope )

Definitely lower. I'm thinking about 76-80.

AND can somebody explain wtf does the trapezoidal rule gives a better estimate than the simpsons rule ?? LMAO wtf.

 

[NFmusic1995]

We should have a proper person check this to find the answers so we can checK

 

[tutorhunt]

im calling b6 cut off at 76/77

I wrote down that the thingy was in shape of a trapazoid?

The shape of the tent was actually close to two trapeziums... So the trapezoidal rule gave a better estimate as it split the area into two trapeziums that would have been roughly the same as the actual shape of the tent.. If that makes sense lol

ME TOO AHHAHAHAHAHAH (well i said trapezium)

 

[blinx96]

nek minute the BOS decide not to scale the exams this year :/

 

[tutorhunt]

simpson rule employs rectangles, whilst trapezoidal employs trapeziums.
diagram shaped like a trapezium, thus trapeziums would better fit the area

I hope you're right cause that is what I wrote haha

That's what I said. Its the only logical answer.

damm haha, i said something like that, i said it uses trapeziums to calculate the area which is more accurate than simpsons rule in this case, and drew a tiny diagram
