Arsey's S15 S2 Model Answers

Ial s2 model solution????

Any idea when the IAL S2 model solutions will be posted?

s2 edexcel: if there is a simple 2 marker asking for variance (2015 s2 uk), would i lose 2 marks for just writing down the correct answer (without the equation)the mark scheme looked a little odd: M1: (0.5+0)^2/12 (This was a formula , simple formula we needed for the question)  M1A1  A1: awrt 0.0208 or 1/48 awrt 2.08 and it seemed that getting the answer right, with no working would lose 2 marks? as M0 A1 is not allowed sorry to be so paranoid, I'm just very on the edge of the grade i need for my uni !!! thanks

very high boundaries

75 = 100ums
71 = 90ums
67 = 80ums
59 = 70ums

did anyone else get an unexpected mark in S2?

nah; unexpected marks in s3, fp3 and m1 though. What was your mark?

As in lower than you thought?

got 85. Was expecting 100. It makes no sense. After the exam I had stored my answers in my calculator and checked it against Arsey's answers and all my answers were right. I missed my A* in further because of this nonsense. I'm fully confident my script was mismarked

That's ridiculous, have you gone for a remark?

yeah

I feel like this for m1 and s1. I predicted high 90s in both from the unofficial mark schemes and the released grade boundaries but ended up with 87 and 77(I mean 77 in s1:/)

Surely I can't have got it that wrong with?

I guess just send it back for a remark

Yeah I'm going to get it remarked. I checked results plus and turns out I lost 5 marks on question 1 (nonsense) and 1 mark on question 5b.

I'm in the exact same situation with S2 and FP2. only made one mistake on fp2 (by comparing to arseys markscheme that is) and that was one of the one mark questions at the end of the paper but unded up with 79 ums in both some how and missed the A* in further

Yeah it's weird. I'm going to request my script back first then send it for a remark

Hope it turns out alright. Think it goes to a senior examiner now so if your answers were correct you should be sure to get the 100.
I feel like I've been overmarked in M1, like someone may actually have taken my correct crossed out workings even though they were replaced and used them to get me to the 100 I seemed to have worked out was impossible...slightly undermarked in FP3 too I reckon.
