# OCR FSMQ Additional Maths - 20th June 2017 watch

1. (Original post by Lemur14)
Depends on your school. It will definitely start between 1pm and 2pm, and it lasts for 2 hours.
My school starts at 1, although many will start at 1:30, or even 2.

Learned something new haha
2. Yeah, I'm not looking for the specific minute. My only concern is that I get into school for 12:30pm only to find out its a morning exam. I checked my schools exam timetable and the exams boards but I'm still paranoid.

Im going into school at 8.30 just so I can spend the first 2 to 3 hours with my teacher really nailing the hard qiestions so im readybfor the test. I dunno how hard it will be this year. Hoping to get an A but lets see.

Good Luck to everyone doing the exam.

5. How did the exam go for you guys?? I found the second last question time consuming and spent too much time on it. Overall, it went well and hopefully I get good marks.

I found the question on inequalities time consuming, must have spent 15 minutes on it. You reckon the boundary for A will be in the 60s or 70s?
7. Can someone put answers in plz

Can someone put answers in plz
Yeah why not? Please suggest corrections if you find mistakes
1. -1<x<2
2. y=1.5x-5.5 (or equivalent)
3. y=5x-16
4i) 2root5
ii) (-1,6)
5i) x^2+y^2=50
ii) (7,1) and (5,5)
6i) Find factors of 6, solve x where f(x) = 0, answer is -3
ii) x=-3, 2+root2, 2-root2
7i) 56/3
ii) Negative area cancels out positive area on graph, so total area is negative, therefore...
8. 0.132 (or as a fraction)
9i) Integrate and sub in 0 and 8, to get 0
ii) 56m
iii) Prove = (2b^2+2c^2-a^2)/4
iv) 2root10
11i) Sub x=0 (no fertiliser) to get c=24
ii) a=9/2 (sim equation)
iii) 3kg per plot - 37.5 tonnes yield
12i) x+3y≥30
ii) x≤15, y≤8
iii) 2x+3y≤48 (after simplifying)
v) 15 minibuses, 5 coaches = £2250
vi) 6 minibuses, 8 coaches = £1800
13ai) 2hr18min
ii) 2hr30min
iii) (x/5) + (sqrt(x^2-8x+25))/2
13b) x=2.7km => 2.1747 hours, which was minimum
14i) 46.9m
ii) 1052m
iii) 8.37°

Yeah. It was a bit long. I hope the grade boundary is between 60 to 70
10. What does everyone think grade boundaries will be?
11. Quick question:
For the question with the time and you had to find the distance (the second part of the question), should I have integrated as the distance is the area under the curve?
I integrated the velocity equation to make it a distance equation, then substituted t with 8 to get 53m I think. I suppose that's wrong?

How the hell did you remember all these answers bro? You're a god, lol!

My school has the largest cohort of Yr11 FSMQ takers in the country (170 students) and we exit poll the students each year on likely percentage score.

For the past fifteen years we have predicted the A boundary to within two percentage points. Our exit poll prediction this year is 74%.

Most good schools took the 2016 paper as a sign of things to come and put some serious time in with students, and so the relatively easy 2017 paper will see a high number of 80%+ scores.

My name might say so, but I ain't a god; I crammed my answers onto the details label they gave us.

I subbed in 8 and got 56m instead of 53m.
17. Didn't you already had what s equalled as you had to differentiate that to find v? Or am I remembering the wrong question?

18. Actually wait, yeah I think I did get 56. I just know it was 50 something.

That's genius man.

Well good luck to all. I thought it was quite deadly, so did a few of my companions.

That's quite high. I found it alright...Would'nt say it was easy, I totally messed up the last question
