AQA A2 Maths (Old Spec) - Further Pure 2 MFP2 - 22 June 2018 [Exam Discussion]

Original post by Mosa99

how did you guys do? FP2 was an extra module I decided to do. I will lose like 10 marks. Is it enough for a 90 ums????? i messed up FP3 i hope 65-63 are enough for an A* in FP2.

Me too! 4 marks to integrating 1/cosh^2, 4 marks to 1/α^4+1/β^4+1/γ^4, and 2 marks to getting 2 solutions for the y-coordinate.
Just hoping lots if people also missed a couple of 4 markers.
Time was as always the big problem.

Yea time was a killer. What other modules are you doing?

Sameeeeeeee I missed a few questions cause I didn't know what to do XD Couldn't finish the last part of the roots of polynomials question, only did half of the proof for question 3, couldn't find the y-coordinate thing (I got coshy = 5/12 or something), couldn't do the last part of question 9, and couldn't do the last part of the question 'find the least value of |z|. But overall, the paper wasn't as horrendous as FP3 haha

For |z| I think I drew a line through the origin and perpendicular to L, worked out the point of intersection then the length

**** me that was bad. Probably lost 15-20 marks so bye A*

Does anybody remember the questions? I'd be interested in trying to guess how bad I did

Harder than last year due to time, but doable nonetheless. I think grade boundaries probably same as last year or maybe 1-2 marks lower for an A*.

Anyone wanna do a mark scheme

Same here, but the grade boundaries are always relatively low, so you should still get at least an A even after losing 15-20marks~

Oh don't worry about it, I don't know if it's the right way anyway and I got very confused by the roots of polynomial question as well

Unofficial markscheme?

Honestly think I missed out/half-arsed about 15 marks lmao so taking that into account and obvious failures elsewhere I'm looking at a B if i'm very lucky :smile:

Nah I'm pretty sure that's the right method. |z| would be minimised when the angle between the line L and |z| are perpendicular, so you've probably got those 4 marks haha~

The polynomial question - I did half of it and got to something like 16/81 [sum of (double products)⁴], but then ran out of time. It's probably wrong anyway~~

Don't know if this helps, but all I remember is this:

For the 1st part, you had to express cos(5theta) in terms of powers of cos(theta). Then you had to find the value of cos²(theta) (or something) when cos(5theta) = 0. The last part was something about the product of 2 of the roots or something.

Probably doesn't help much, but I tried😂

Yes it really helps!!!!!!!!!!
I have been panic for an hour about that if I missed out the last question!!!
But now, I can see that I didn’t miss it out since I did the question you described!
Thank you so much!!! You saved my day!!!!!!!!
