IKr, same here!

a=8.88 m/s^2 T=1.75 N I'm sure about this, matched with a lot people

Yea thats right!..I got it wrong though..didnt take both the resistances into account so i got acceleration as 9.2 and hence got the tension wrong..i hope the examiner gives me ECF

InshAllah

CIE is aiming to spike the standards in maths papers from now on, I reckon.

 

[Freaked out]

is it possible for an A to be at 28

 

[Soldier313]

I wrote one too! DAMN!!! SHOOT! SHIT MAN! simple concept! i messed up question 6 part b and from what ppl are saying in this thread i probably messed up question 5 part b too! also, someone told me you lose marks if you dont write all the signs for integration and derivation. + aggr graph paper pe graphs na bnaao to number kat-te hain! Maine normal answer sheet pe bnaa diye!

hey nah it said sketchhhh!!!! and sketch means no graph paper needed! that's as far as i know atleast:/

 

[midhat_moon]

hope no one is!! hope the GT will be low..the lowest..the GT needs to make a record by being the lowest this year...

hahaha yeaaahhh, i was praying for the exact same thing ke this year, bas 1 miracle, one miraculously loww GT

IKr, same here!

not just you,every-freaking-body!! except those geniuses!

 

[aditya avhad]

^Lol!!!!

 

[Sidma khan]

it was really hard, ill probably lose around 10-12 marks. i usually get 48-49 out of 50 in other papers. this paper will probably have the lowest percentile, probably around 32 for an A. so dont worry

Totally Agree with u!

 

[busy bee]

i just hope p3 is easyyy and NOT lengthy like p1 and p4 -_-

For Q4 i wrote
Horizontal components :-
R(->) :- F = Tcos25

same way for the vertical.is dat correct??

 

[rehan751]

You remembered the values of all the questions.. Well all your answers match mine except for Q.6 part (i) where i didn't include change in PE

your last graph of displacement is slightly wrong
every thing else seems perfect

 

[Taha Nemat]

it is somewhat like this. after the block hits the wall and starts to go back. the speed is greater so rate of decrease in displacement is more. then speed slows down so rate of decrease in displacement also slows down.
