I can't remember this one 2 marker answer I put in there but taking that out I got 73/75

[MathMad]

how many marks do you think you would need to achieve for an A, B, C and D out of the 75 marks in total?

57 1/6 or something like that

I got 56.7, not sure why I was a little off, do you think that's close enough?

[JakeMachinima]

I read the first question wrong. I thought it was 1 oh dear god.

[lou_100]

SO annoyed. I made one teeny tiny error on 8c and got the wrong x.

seeing as 8d and e follow on from c's answer...how many marks would I lose for doing the correct method and everything just wrong values? Would it be :

1) all the marks for just getting it wrong
2) I'd get one out of two for each d and e for method marks
or 3) error carried forward so wouldn't lose marks on d and e, just c?

[Obadetona]

Woah... I think I got 100%

[Bread Basket]

Didn't actually know what the trapezium rule was due to missing lessons and not really revising. Scuppered my chance of 100 but that was unlikely. Looking for 90 now.

Cheers Arsey.

for the question 3)c) circle my method is correct but i got the wrong y values how many marks would i lose?

[xxZazxx]

for the differentiation if i left x as the cube root of 30/pi will i still get the full marks for x...it is an exact equivalent...or did it say to some sig figures :s

[Phoebe307]

I couldn't work out the log question, so I did trial and error and got the right answer - if you get the right answer do you automatically get all the marks?

SON OF A *****!!!!

Well there goes 100 out the window!

.....

On the integration question, I made a trapezium out of the x values instead of the y values so I had:

(9+2)x7
---------
2

so the area of my trapezium was wrong How many marks would I lose? My method was exactly the same as yours though!

I don't think it asked for sig figs so it should be fine

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.

hey....i just had a few questions....for the integration i used the wrong limits completely (they werent from the answer before). how many marks would i lose for that?...and for the perimeter of the sector i worked out triangle...how many would i lose for that?

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

Well done. I flopped on the cos2x question.

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)?

i did the exact same thing! hope this is allowed

[Prash3200165]

Should be full marks, maybe a few lost for not enough working out shown

kajenkjnaekfjkaenf thats what i got

It was my stupid calculator :'(

[TanishaBellum]

I reckon i got like 54 :/ log and trig question f***** me up!

[x_MissyB_x]

wheres part a in Q3 plz

I did the same thing.

I'm pretty sure you get the marks because it doesn't specify any sig figures but i've asked arsey.
