paper 42

wow how did u get these ?

 

[FRENZYAMU]

In June 2012 a friend of mine discussed the whole paper with a boy who got distinction in June 2012.
He expected
75/75 in P1
50/50 in S1
45 /50 in M1
60/75 in P3

He still scored a B

You never know what is Cambridge upto

woahhhhh i seriously pray that doesnt happen again with any1

here are all the solved answers for paper 42..... thanks to scalar

who solvd the papers btw??? is it 100% confirm?pls reply faaaaaaaast

paper 42

you can't be the one who took these pictures??

guys i need help i did 1ii wrong
2 3 5 7 all right
4 i din't solve with 4 rules i solved with work and energy so I got S =12 so it ruined ii
6 i did i ii right but iii i got the area of shaded part and substituted with the 20 and 26 in equation
how much should I get plz answer

you kind of confused me but,
4i) has 5 marks, if you did ALL of it wrong then you lose them
If your STEPS in ii) were correct you only lose 1 mark
6iii) substituted in what? did you write any other stuff for that question?
that's 6 marks apart from 6iii because I don't understand what did you do

what if i lost 9 on paper 12 and 14 on paper 42 could i get an A

You get an A for sure in paper 12
for 42 it's possibly an A but most likely a B, but for the total I'd say A because paper 12's marks will make it up

who solvd the papers btw??? is it 100% confirm?pls reply faaaaaaaast

A teacher or a student, in both cases no it isn't 100% all correct

 

[CIE xams]

i guess shaded area is correct by scalar

thnx very much
in 6 i got the area between 20 and 26 sec then in the equation given substituted by 26 - substituted by 20 they was the same

hey first s will be 0.6m and second distance when A was resting on ground was 1.--- something i don't remember u did something wrong my friend what was ur acceleration value a=-2.-- something??

:O wat was marks for this qp?..

 

[menna1234]

i guess shaded area is correct by scalar

no but they asked to shade only between 20 to 26, i think its not correct

 

[Mohamed Suhail]

i agree they said shade from 20<t<26

Is the shading is from the beginning to t in exc 6 ARE YOU SUREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

its wrong area shaded

 

[mohammed yasser]

A

its wrong area shaded

Are you sure because I did it like them

 

[CIE xams]

scalar's response abt graph:
the requirement for question 6b) was to shade the region representing "s" for a value of t where 20<t<26 (with equality included)
check question paper to see the exact requirement

"s" was the displacement from O - so was area under the graph starting from t=0 to any value between 20 and 26.. you could stop at 20, stop at any value between or stop at 26.. the correct shading in part b) was useful for part c) to get s when t=20

I think some students misunderstood the requirement, instead of reading "shade the region representing s for a value of t where t is between" they understood "shade the region representing s for t between".

Are you surrrrre

 

[CIE xams]

i agree wid scalar coz shading frm 20 to 26 only represents the distance at this time interval,not displacement from O...

 

[CIE xams]

YES sure coz scalar's the one who solvd the paper....i agree wid his ans

 

[saadgujjar]

YES sure coz scalar's the one who solvd the paper....i agree wid his ans

I dont agree all shaded the region from 20-26

All I will say is that Im fucked and Only p3 can save my glorious ass
