General Thoughts: Mathematics Extension 2 (3 Viewers)

[panda15]

I was expecting more integration (i mean they put partial fractions and no integration. WTF!!!) and was expecting more volume questions.

Yeah me too. Those were 2 of the 3 topics i expected to be big players in the exam, and barely anything was asked on them,

 

[ForOneEon]

ah i let z=x+iy and w=a+ib and it worked out for me too

I did this and screwed it up at the end! FUUU!

[spongebob1]

is 60 - 70 raw mark good? anyone know what that roughly correlates to for this exam

 

[RafH]

i) 0.2401

ii)

I think these were my answers.

How come its 7C1 for the second one?

I put:
8C3 (0.2401)^3 (0.7699)^5 + 8C4 (0.2401)^4 (0.7699)^4 + 8C5 (0.2401)^5 (0.7699)^3 + 8C6 (0.2401)^6 (0.7699)^2 + 8C7 (0.2401)^7 (0.7699)^1 + 8C8 (0.2401)^8

Is that right? =/

95 raw, is that a state rank?

Phew, panicked for a sec there and everyone was agreeing with u aswell! LOL =)

terry lee must be having trouble

*his minions

truong tutors and all his asian ruse minions failed the exam

 

[Makematics]

Im pretty sure terry never releases his solutions this early??

 

[superSAIyan2]

the test was kinda hard. made like 9 or 10 mistakes
1. didnt attempt the zw - wz question but realised how to do it at home
2. for the car question, i misread the question and did 4 cars instead of 8. i think i'll only lose 1 though.
etc

Let's just say maybe you won't need to wait for terry lee

There was actually not much poly at ALL. Freaking poly was so easy and they only gave around 5-6 marks of polynomials. Overall i think it was very biased towards complex/conics/mechanics in comparison to last year.
OH AND harder 3u.

Really? I was expecting them to get 90+ raw... How do you know this??

Lol. How do you know? I wonder what Truong is thinking now that he's probably seen the exam.

 

[A-Tan]

Ahhhhhhhh. Forgot to shade in at the end.

Ruse and NSB have around 4 100% raw each. So I'm guessing cut off will be higher

 

[Makematics]

If anyone was wondering how the marks were distributed across topics:
Complex numbers - 18
Polynomials - 6
Conics - 8
Graphs - 8
Integration - 16
Volumes - 5
Mechanics - 15
Harder 3u - 24

Didnt realise there was so much complex numbers haha

Pretty happy that there wasn't really inequalities. And our predictions about mechanics came true.
