Arsey's S1 Edexcel Summer 2013 Model Solutions BOTH PAPERS

I think you'll be alright, as the difference between 1000 and 500 is 500 and so you only need to find the temperature change for 500, if that makes any sense?

Besides, it's what Arsesy did in via model answer anyway.. Just worried 'cause I got 7.9 instead of 7.5

Generally, you will be awarded 1 (method) mark for "any" Venn diagram, any other marks would depend on any further working/notation.

Thanks! Sorry about the handwriting, but I'm not going to get out of bed and use a desk just so people can read it! Just be grateful it's not my head of department posting - people get used to my writing in time, but I still can't read his after 20 years.

In question 4a I have used the 3 sig fig mean value (24.2) instead of calculator value to calculate the standard deviation and the value I got is 9.26 instead of 9.29. How many marks will I be deducted?
And how many raw mark will get full UMS for this paper?

Hi Arsey, have you got my quote about uploading C4 Notes?
I'm really struggling with C4 Vectors and application bit of Differentiation, so I would really appreciate your help please. Thank you.

Check out my previous C4 threads. I may have put some up.

Thanks for replying back! Okay! Ive got to smash the C2 paper now!

You have an amazing memory to remember 9.26! Previous mark schemes often give a 'range' of answers for the standard deviation; I can't imagine you would lose any marks? I'm not entirely sure though.

For q 6 if you used the big table rather than the little table, the values are slightly different, would you still get the marks?

Hi; these are my worked answers with comments.

I can't compete with Arsey for promptness, but it might be useful for people to see an alternative set of worked answers, with commentary.

I really don't know how Arsey gets hold of the papers so quickly. At my college, the teachers get the hard-copy 3 or 4 days after the exam. Last year, I got a stern summons from the Exams 0fficer when she heard I had been distributing worked answers a day or two after the exam; she was worried that an exam-paper had been smuggled out of the exam-room after the exam and had reached the teachers - which would be a sacking offence for someone, I suspect. I had to explain that the "Edexcel Emporium" website for maths teachers posts the papers the next working day. (The S1 paper has still not been posted, as it is Saturday; I downloaded Arsey's answers and snipped the questions so I could answer them without being influenced by his answers.)

I sometimes think Arsey must have some special arrangement with Edexcel, especially as he seems to refrain from criticising them even when they are being particularly ... shall we say ... individualistic.

I'll probably post M2, M3, M4 and M5 later.

[Attaching the file didn't work; I'll try again.] Ah, the file's too big, but I didn't get any error-message. I'll split it. What a waste of my and your time, and TSR's storage - the combined size of the 5 separate files is far bigger than the original single file!

Lol I was thinking the same thing when I read the box plot question. How sexist!

Arsey, could you please upload the model answer for the S1 international paper? your work will be very much appreciated

Why is everyone getting so upset over the box plot question, for got sake page 61 edexcel textbook, although at little less extreme than in the exam, it still shows that generally they are around the same level, /girls have a higher median score etc.

I don't get why feminazis are all getting mad about a question which was there PURELY to contextualise the data and allow students to sit the specified exam question. I'm sure if you sift through exam papers at some point there will be one with females exceeding males.

Haha "feminazis" i like that. I have actually come across a question in stats where females were exceeding males -good point.

I hope I get an A , i didnt want histograms to come up because I could do EVERYTHING else and I go and mess up the paper, so if I resit next year Ill probably do worse and therell probably be a histogram question.

Low grade boundaries please (Wont happen _)

ive done exactly the same diagram as Arsey has done pretty much , but i think i included a zero in the Bus circle but in the rest of the sample space ( rest of the box ) i think i left it blank rather than 0 , so maybe 3/4 for that ?
