54/70 = 92 scaled....right? :S

 

[anomalousdecay]

66 will probs be more than 98 aligned

This. Scaled is different and is only for ATAR purposes. 98 scaled aggregate will usually require a 94 aligned which requires around 63/70 raw.

52/70

I'll take that. What will that align to considering the difficulty level of this years paper? (Idk if it was considered easy or hard... I didn't prepare much. Smashed everything up until Q16..... 4/15 -.-)

Will u lose a mark in question 11.f) if u went 1/3[tan^-1(e) - tan^-1(1)] = 0.144 in radian form, instead of 1/3[tan^-1(e) -pi/4] ?

awks, no q16

Should align to at least 90, or 90+

Don't think so.

 

[Samir97]

The only solution is to do Maths at uni.

Yo Carrot! 59-60 is my raw in the 3U test, what could that align to?

 

[obliviousninja]

Am I the only idiot not to get newton's method. I'm kicking myself about it. so pissed. BAM two marks down the drain.

for the raindrop question, i THINK i wrote 0.62 seconds LOL, forgot to times the 10^2 in calculator, so would i lose a mark ?
i mean i did write the "exact value" ..

 

[RealiseNothing]

I think overall it was a fairly tough 3U exam especially compared to last years, but not that unbelievably so when you compare it to some of the exams from the early 2000s. Up to question 14 was fairly easy, and the induction was fine too. i'm estimating about a 56-57/70. how do you guys think that would align? from what i've seen i'd guess about a 46/50? or am i being too hopeful?

If it aligns like I think it will (and carrot agreed with me), then that would be a 47 more than likely.

probs will lose a mark...

Hey do u get /50 or /100 for 3u if u do 4u? in my report I got /50, though I heard its /100 for 4u peeps? What would 62/70 be /50 and /100?

/100

just double the /50 mark lol, not calculated differently.

 

[hayabusaboston]

/100

but wat u reckon 62/70 aligns to?

 

[iBibah]

but wat u reckon 62/70 aligns to?

96-97 im guessing

Did the same. Would we loose a mark for doing decimal value instead of exact? The question didn't specify exact value from what I remember.

 

[Makematics]

/100

just double the /50 mark lol, not calculated differently.

Wait so it cant be an odd number??

 

[iBibah]

45.5 would round up to 46/50

But out of 100 it would be 91.

 

[obliviousninja]

they dont give 1/2 marks.

 

[Recondit]

Would 53/70 align to 91 or 92? Since this only counts as 1unit for me, then would it be 46/50?
