How did you guys find the FP2 IAL paper? I think the GCE paper was quite easy compared to the FP2 paper. Did anyone else think FP2 IAL paper was too lengthy? Everyone in my school found it really difficult. It was impossible to finish the paper in 1.5 hours

it looks that only you did that paper ...

I'll just post my solutions for the IAL Fp2 paper here1. -2<x<1 and -5<x<-42. a = 5 and b = 113
3. complex loci: circle with centre (0, -1/2) and radius sqt 5/4 and for inequality shade region inside circle
4. cotx taylor series at x=pi/3 can be found on wolfram alpha. Or someone could screenshot it
5. 1st ode something along the lines of y^2 = 1/((e^-x^2)/3 + c*e^2x^2)
6. 2nd ode something like y = -2/5e^-x + 3/10e^3x + something cosx and something sinx
7. polar cordinates area under curve a = 4/3 (or 3/4 .. i dont remember correctly)
8. the integral solution came out to be (-5sqt2/192 + 1/24)

whaaaat?

I'm pretty sure I took the IAL paper too (HK)... there were no transformation questions

well so for one of the questions in my paper there was a 2nd order differential equation and it asked us to use the PI 3e^(-x)cos3x + Ae^(-x)sin3x. I got everything right EXCEPT the value of A (-12 A + 12 = 0, A = -1) (full: 5m (?))

Part (b) was auxiliary equation, so not a problem. (full: 4m)

Part (c) was specific solution though. How many marks do you think I lost there? (full: 5m)

This discussion is 2 years old. I think u will loose the last A1 mark in part a and another mark for the particular solution at the end since it was a simple arithmetic error only. Our exam was pretty hard compared to the simple edexcel exam, I'd say the grade boundaries have to be around 62 for A similar to the 2014 IAL exam.
