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

You think a B will be around 46? Need around 65 UMS in that for A overall and think I got around 50 marks you think I've done it?

I'll gave your 2009's

50 - 80UMS
44- 70UMS
38 - 60UMS

It's not likely 2015 will be higher than that but i'm not sure, waiting for larger sample on pull.

For the reduction formulae part b was it ok to evaluate -sin^n-lxcosx with pi/2 and 0 as limits and say this was equal to zero. so, In= (n-1)/nIn-2 THEN say that since n is odd and n>=3 that this always will be multiplied by I(1) ie. I subscript 1. Then, calculate this integral which= 1 SO In=blah blah*1 = given

Im scared i dropped marks in reduction for lack of explanation.

Hey guys anyone did IAL f3,?

I did. It wasn't that hard, just a bit long.

If you couldn't do Q8 part (c) then you clearly didn't do last years paper - it was literally exactly the same method for the question using the C3 formulas

That's what i thought i used factor formula and got gradient of two general points (so grad of chord) as -0.5cot(beta+alpha/2)

What do you feel in comparison with previous paper, especially hard ones - 2014 and 2009, i think 2015 is not that hard but wired and some less able students will preform badly

Not sure i only did 2014. It was harder then 2014.
