Okay that was suspiciously easy.

Brilliant exam couldn't be happier everything I hoped for came up and nothing too difficult! still annoyed that I'm more than likely not going to get my A because on Paper 1 :mad:

westernfrenzy

Seemed nicer than P1. Probably got a lot wrong though

What was the slope of P? I just had to make it up which would have lost me a few marks

Grand paper, now for Irish.

I believe it was -1, it told you they were both equally spaced or whatever so I just gave it the points (5,0) and (0,5) then used the slope formula

1 I think?

Upward sloping from left to right so would it not be positive?

bmea

Ya it would have been positive

I was thinking that myself but i got -1 when i worked it out probably made a small mistake :P

It was 1. It was split equally. Perpendicular slope was -1.

Was not too bad.. hopefully pass- worthy. Only thing was I don't remember ever doing enlargements.. threw in some numbers and drew a triangle.. praying for some attempt marks there

I thought the enlargement question was lovely, if I did it right.

matii10

Same here. Never done enlargements and just guessed that the large triangle is 1.5 times bigger than the small one.

TheSunderz

yeh was very easy tbh only part I wasnt sure on was question 9 part e on that formula thing or trial. Actually what did people get for the equation on the secound circle, radios wise ?

ko3p

Slope was 1. All you had to do was get Tan45.

What was the Empirical Rule?

electromix

so much better than paper 1. Want to pass so bad.

Famoso

I hadn't a clue of the Slope of P, so just picked 3 and continued on doing the rest of the question with that slope. Will I still get a few marks?

It just states that, in a normal distribution, 99.7% of data will fall within three standard deviatons of the mean. You can break it down into 68% within one SD and 95% within two SDs.

I picked 2, and you only lose marks for the first part, you'll be marked correctly for the rest (assuming you did the question right.)

NoDruidsPlease

Paper two was exactly what I needed, might actually pass maths now.

For the very first question was it 10! diveded by 6 ???? Or 10x10x10x10x10x10 ????

Oh God, I missed the part where it said that the numbers may be repeated. So I presume I got the whole first page wrong because of that fact. I've got 10x9x8x7x6x5 and I assume that the correct answer is 10x10x10x10x10x10.

Jamies15

Actually was that slope of P definitely 1? I've been talking to a couple of people in my year who dropped from honours and I would assume know more than me and they were saying it was -1.

I just can't understand how it could be given that it sloped upwards from left to right, is it ever possible for that to be anything but positive?

Messed up on the very first question about the bank pin, I wouldn't mind but I knew how to do it and did it right in the mock.

ConM96

I was a reader for a candidate in the exam today and am currently studying to be a maths teacher and I can confirm that the slope was 1 and the perpendicular slope was -1. If any of you have any other questions about any of the questions on today's exam feel free to ask and I can provide you with the correct ways to do out the questions.

Just seeing aswell some of you are asking about the pin question . The first part was 10^6.

Question:Did any constructions come up? Waa revising them with my sister last night.

An Enlargement came up but that was it

Horrible paper.
