35
287
031.2

To what was the answer 287? I had 277 i guess

 

[Mahnoor Ahmad]

i gave answer in cm. We were supposed to give it in metres?

Well, they said calculate so I used Pythagoras.

 

[anamta]

I don't think the percentile will go any higher.For some,paper went awesome but at the same time there were many cringing afterwards so I guess the percentile will remain low and you have a good chance at A

yupp i am the one :/ my P2 went really bad still hoping to get an A atleast :/

 

[Saad Mughal]

What happens if i wrote 2? is it wrong? because i rounded off lydia's amount to 8562 so i couldn't give the answer exact because they tell us to round it off.

Money answers should be kept to 2 decimal places, this is in the examiner tips.

Yes.

The shortest distance.
Sin 35 * 500 = 287.

My A* is flung out of the window. How was SR (7.5, 3.0)?

 

[Mahnoor Ahmad]

how did you find PQR?

The shortest distance.
Sin 35 * 500 = 287.

 

[Saad Mughal]

My A* is flung out of the window. How was SR (7.5, 3.0)?

PQ = (-9 18).
PS = (-4.5 9)
PR = (3 12)
SR = PR - PS
SR = (3+4.5 12-9) = (7.5 3.0)

 

[Saad Mughal]

how did you find PQR?

Alternate angle with the bearings.
PQR = 65 - (210-180) = 35.

 

[Kamihus]

The shortest distance.
Sin 35 * 500 = 287.

Yes, i hope i got the same and entered into my calculator wrong
Used the same method (hopefully did no silly mistake)

Whatabout relative velocity?

 

[Mahnoor Ahmad]

Alternate angle with the bearings.
PQR = 65 - (210-180) = 35.

thinking of giving in november. So far i have lost 5 to 6 marks in p2 and 5 to 7 in p1. My A* is gone because there could be more to be lost.

 

[redd]

ok just think u get wages for per hour u worked for 4hrs 45mins ur 45mins would go waste? absolutely nO

well, we cant say anything... markscheme will tell us.

No it's not. A* is normally at 162/180. Which means you can still lose a further 3-4 marks.

 

[Kamihus]

No it's not. A* is normally at 162/180. Which means you can still lose a further 3-4 marks.

Yes, and due to low thresholds expected another 3 or 4 too.

 

[Mahnoor Ahmad]

Are you sure? thanks. But earlier I heard somebody was going to get 180?

No it's not. A* is normally at 162/180. Which means you can still lose a further 3-4 marks.

 

[Saad Mughal]

Are you sure? thanks. But earlier I head somebody was going to get 180?

That doesn't make a difference to the overall thresholds.
100% are achieved by students every year.

it is clearly wriiten on the front of the question paper "if the answer is not exact, give the answer to three significant figures."
this means that we have to only round if the answer is not exact!
in the lydia's question, the answers were exact!

I know but the examiner tips further clarify things for these sort of questions.
