1. For the second question, did they give you the gradient function or did you have to derive it?
2. (Original post by 123Master321)
Was the binomial expansion question x= 1.05
I got 0.95, as x = 1- σ

I checked the answer with my calculator as it was 1.05 and x = 1+σ
4. Anyone else felt like that exam was brutal?

Is there an unofficial mark scheme too?

They gave it, we had to find the curve equation
6. (Original post by Ricdave)
I got 400m too
S = ut + ½ at^2
Car A: = 0(t) + ½(1.5) t^2
= .75t^2
Car B: = 0(t) +½ (2) t^2
= t^2
.75t^2 +100 = t^2
100= ¼ t^2
t= 20 seconds
S = ut + ½ at^2
= 0(20) + ½ 2(20)^2
=400m
7. welp it was ****

400m i believe or that might have been the wrong question
i get where you came from, but i got 300m

edit scrap that i did get 400m
9. For question 11 how did everyone do the quadratic thing? Also what expressions did you get for the distances?
10. (Original post by etata)
Was I the only one because I've murdered all of the past papers and i think I'll be lucky to pass
^^this is literally me
11. Welp.
GG, OCR. You've successfully managed to piss me off in ways I did not think were imaginable.
Did all of the past papers, thought, 'yeah, this isn't so bad, I'm ready!'
After doing the test, I feel like I've wasted a METRIC S***TON of time revision for a test that is going to make me cry to sleep.
Just... so many questions where I was completely baffled.
12. For the first triangle question, with the bounds, I crossed out all my working and then wrote a note that the examiner should use my workings (they were fully legible).... do you think that's okay?

I know, no binomial distribution too
I KNOW RIGHT and that is my favourite area

OP=400-25t and OQ=100-20t

Use Pythagoras to find length PQ (xm) which gave something like 170,000-24,000t+1025t^2.

Differentiate this and set it equal to 0 to find the minimum value of t which you the substituted into the equation above to get 171.8m.
15. Like 400-25t, and the 100-20t, I got the answer to be 170 metres as the smallest length of X. Don't know if it's right.

Yep don't worry about it the examiners are told to mark crossed out work (unless you provided a replacement answer) so yes it should be fine

Well a least I have about 6 marks now.
On my way to an E

same
19. What does everyone think the grade boundaries will be? I think I didn't answer a round 25 marks and I want an A:/
