AS math 9709/May June/2018/ Paper 12 Hard Or Easy?

[muhammad ali 69]

I just had my AS math exam paper 12 a few hours ago, and I felt it was very difficult and long, Please share your experience

it was okay, but agreed a few ques looked easy but were tricky. Was this the reaction of your whole batch?

They too found it difficult. Did you finish the whole exam paper before time?

 

[ThePacifics]

yUP. i found a few ques difficult too but it was manageable.
what would you think the grade boundaries would be this time i hope they are low because a lot of us found it a little tricky to deal with

 

[ThePacifics]

btw what was your variant?

 

[Julius696969]

This paper sodomized the living shit out of me. It's WAY harder compared to '17. Too bad we got the short end of the stick.

 

[abbas haider]

It was tricky..btw what were the range of angles we had to find by using graphs of trig ratios (i guessed 270 <x<360 probably wrong)

 

[ThePacifics]

what variant did yall give is what im asking

 

[Roshan Nepal]

What is the expected threshold for A?

 

[abbas haider]

p12

 

[muhammad ali 69]

I gave variant 2 basically paper 12, and I think an A would probably be a 54 or 53. Also, did you guys finish the whole paper properly?

>54
Most times it's around 60.

 

[A*****]

It wasn't difficult but it was extremely lengthy!!!

binomial, a = 3
k<9 and k = 11

a = 8000 , r = 1.02

h= 1 k =22

a = 7 b= -4 , for no solution k > 7 , and k < 3

x = 146 , 323
range for which 2cos > -3sin , 0 >x> 146

 

[Akkkkk]

Will the threshold be so low? Like you mentioned around 54 etc. I can’t recall threshold being this low in the past years

Anybody took p13? Thank god i came out alive, i estimated i lost 15 marks lets hope that grade threshold is low this year

x = 146 , 323

I got h as 3 and k as 25

There were some years where it was around 54 or 55 in the October/November sessions. But this was harder than those papers.

did you reverse the gradient of the perpendicular bisector>? then use y 2 - y1 / x2 -x1 = to that gradient? this gives h.
then use mid point of AB and replace it into the equation of the bisector to get k

A = ( h,h) , B = 4(h) +6 , 5h)
