# Edexcel FP3 June 2015 - Official Thread watch

1. I think the paper was hard, I didn't finish the whole paper
2. (Original post by cogito.)
How's the paper and how's the feeling about conics?

It was good - feeling a 100UMS

You?
3. 70 for 100UMS ?

I feel not ok xD. Didn't finish last question

Conic part was kind of like last years - so if you did that you'd have been fine

Me too

Haha! Core maths is the best for me anyway - should make up for some lost marks in M2/3 and D1
8. Method for part c of the last question?
9. how on earth did you do the last question? I didnt even understand what i wa being asked to find?

Thanks for the irrational eigenvectors too,

area of oqr = xy?

bye bye a*

has it even been that low?

scribble soemthing down and hope thats right! i could not do it!

Same as last years basically

You have the general point, P(2cos(x), sin(x))

Then let 2 points with x=alpha, x=beta or something

Find the gradient, let it equal =m (constant)

Find the midpoint of the 2 points

Then rearrange to eliminate the variables and you should have got

Y=(-1/4m)X

I got OQR=1

Had like Q(e^t, e^t) and R(e^-t, -e^-t) and find OQ and OR by Pythagoras and then area = 1 therefore independent of variable 't'
14. Ok, i feel fked,
Q1- hyperbolic - easy 1/4ln5/3
Q2 - hyperbolic in exponential - normal
Q3 - eigenvector - normal 2,2+-sqrt(2)
Q4 - integration for (x+1)^2-4 - easy
Q5 - conics? hyperbola - c) is hard
Q6 - vectors - slightly easy than before
Q7 - reduction? strange - normal/hard 8/105
Q8 - conics - hard

Comparing to the hardest paper in history i.e. 2009 or 2014
for 2009 as comparison to 2015
Q1. identical - easier
Q2. vector - easier
Q3. eigenvector - same/easier (they have integer eigenvalues)
Q4.differentiation - normal and little bit hard
Q5. reduction - harder but regular rather than 2015's form
Q6. hyperbola - easier than Q8 in 2015
Q7. vector - slightly harder
Q8. integration - same

and for 2009 is 50 for 80UMS, so 2015 will be -2/3 maximum

Predicted UMS as Minimum (don't think will go lower)

65 - 100UMS
59 - 90UMS
52 - 80UMS

at least you can get an A, I maybe get b or c in fp3😭

was a tough paper, hope you did well mate. very annoyed at my performance
17. p = 1/4
q = 4/3?
18. (Original post by Ilovemaths96)
p = 1/4
q = 4/3?
I got 5/3 for q
19. Think I've finally managed to get that A* in FM. Last exam as well.
20. (Original post by elliemoriarty)
I got 5/3 for q
Same i got 5/3
