Boundaries must be high for this one

according to me it was a good paper , but still don't want boundaries to be high

[The_Pen]

I got 2.12

[bong]

Yess i got all correct!!!!!!!!

[Praami]

hated the proof bit ¬¬ i think i only scored one mark for that part. other than that question, it was a really goooooooooooooooooooooooood paper (Y)

[Bread Basket]

Hoping for 77 UMS so I don't have to retake any other units. No horrible questions from my end. Looking at around 85%+ but God knows what % that will end up as because to be honest I figured that the grade boundaries would be insanely high as soon as I saw the last question...

what did people get for the area under the curve or whatever it was?

57 1/6 or something like that

[The_Pen]

I also got 85mm, 364/6 and 15 for the geometric.

I got 1.2 or something for trapezium maybe it was 1.8)

did anyone get the first term on the geometric series equalling to 15, the common ratio being 0.6, and the sum to infinity being 37.5? i got something like that.

yaay i got that =)

[Mtice]

Hadn't learnt the proof.

Rest was easy.

Checked the paper, everything but the proof. So at least 71, I hope.

Looking at the unofficial mark scheme, I got every answer right, so will be 100ums, unless I drop stupid marks in the working out.

[yaboy]

for the trig question say you got the values 39.2,90,140.8 and missed 0 and 180 how many marks would you get?

[justneedhelp]

100% woooooo :d

[Incorrect.]

100

[ArsLongaVitaBrevis]

Just looked through the paper. Full marks!!!!

[Stardust Mirage]

Grade boundries are going to be so HIGH. Just hope ive not made any stupid mistakes -_-

thanks for putting up the answers. For the trig question, I made a silly mistake and got cos2x=-1/5 rather than +1/5. I continued to work out the values using the -1/5 though, at an estimation how many marks do you think i'd lose?

looooool omg i did that @ the start!!!!
Somehow got 120 / 4(pi) = 30(pi)

kajenkjnaekfjkaenf thats what i got

Overall I think this was a very easy paper.


Q1 Binomial Expansion


Standard and no tricky b)




Q2 Logs


Standard, very easy




Q3 Circles


I expected a rearranging into circle form, the rest of the question was very easy, part d) was a joke




Q4 Factor Theorem


Very easy




Q5 Area under a graph by integration


Slightly harder than normal as trapeZia often cause problems




Q6 Trig


I thought this was pretty easy but I understand it has caused quite a few problems




Q7 Trapezium rule


Joke




Q8 Trig


Pretty standard, lots of frameworking.




Q9 Geometric series


I hope you learnt the proof.... rest of the question was straight forward.






I think the boundaries will be really high


Last few June boundaries were 62, 62, 53, 63, 59, 67 for 80ums


I will guess at


100ums - 75
90ums - 70
80ums - 65
70ums - 57
60ums - 50
50ums - 43
40ums - 36


This thread will be locked at somepoint and then unlocked at midnight following the Core 2 examination. I will upload the paper and my solutions to this post.

I will do my best to answer questions about the paper but please try to read the thread first so that I am not answering the same questions lots of times.Here are some links to previous D1 threads, they are worth a read and you will see what the common errors were...

The second link has loads of past papers, mark schemes, model solutions etc




Good luck.

Hi Arsey, cheers for posting a solution.

For 8)c) would it be alright leaving x as the exact answer (ie the cube root of 30 over pi)?

[UWS]

For question 9, I forgot the ar^n at the end for the first step, but did everything else correct so how many marks would I lose?

[meowcat]

I calculated the perimeter of triangle instead of the sector! Haven't read the question properly... How many marks would I lost?
