I'm talking about YOUR graph's gradient, not the other one. It was -0.8.

oops, yes i just realized that the other one is hovering across my mind... well, i dnt remember mine ones...

why u r crying...u gave 4.5 right?...its the correct answer, i gave 5..so i am wrong.

 

[redd]

yes, my gradient was 4. something, i just calculated it

I gave 6. From tangent. I didn't realize the need to differentiate in during the exam, I differentiated it after the exam and realized it was 4.5 and I gave 6 which WILL be out of range, so 1 mark lost.

 

[Ammarfasih]

Will be given 1 mark I guess

i think it was of 3 marks ... :/

Poor me. The only incorrect gradient one.

 

[Saad Mughal]

2 marks, the one previous to this was of 3 marks.

i was a stupid...i differentiated it to be certain yet i took 4.499 as 4.99 and wrote 5.
and i dont think the range will be from 3.5 to 5.5...this is too long and lowers accuracy.

 

[Heyyy]

In the bearing question,what was the answer of part (i)
Can't remember correctly but It was like 35 or something I guess

 

[Heyyy]

2 marks, the one previous to this was of 3 marks.

No,that was 4 marks.The Cosine one

THE RANGE IS ALWAYS this large. Check the mark schemes. But my answer will be out of range.

yes...the first angle PQR was 35...and the last bearing was maybe 032.1 or something like that.

 

[Saad Mughal]

No,that was 4 marks.The Cosine one

Ok.

35
287
031.2

well, if u r so sure..then that will do for me...but i feel soory for u...so whats ur total marks loss?

 

[Heyyy]

35
287
031.2

Yup,exactly the same.
What was part (ii),sorry I am bad at remembering the questions

 

[Saad Mughal]

Shortest distance from P to QR.

3/180 which deprives me completely of the distinction, I had a slight chance with 2/180. There has been ONLY one instance when the range for gradient was, I think, 6-10 or something (for a cubic equation), for quadratic equations it's always 3-5, 6-7, ...

 

[Heyyy]

Shortest distance from P to QR.

Oh yea.
Did you do the question in which we had to satisfy the equation?
What was the distance BC?
I had 970 I guess or something

ohh!...dont worry...3/180 is not bad....but one question: WD is calculated each year comparing the results of that session or it is like the highest achiever throughout all the years?
