Feeling pretty confident about that test. Couple of things, firstly, what did you guys get as the ratios for the last question? I got 4:1 in both but I think that one of them should have been 8:1.

Also, for that question about mobile phones, I got a decimel. My friends, who are really good at maths, got the same. But it would't make sense to have like .3 of a person! I forget my actual answer... It didn't look right anyways.

I think I might just have scraped an A, but I'm happy with a B.

For the ratios, i didnt tun it into numbers, i just kinda wrote the first one ad then ratio to the second one so like
2.Pi.R.H : 2.Pi.2R.2H
and for second 1 Pi.R^2.H : Pi.2R^2.2H

For the mobile phones, a lot of people got decimals, i just did
1421.93 = answer (not actual 1)
You cant have .93 of a girl so approx 1422
It was a terrible question and a lot of people got different things so they might bring down marks on it

Pretty happy with paper 2 came out feeling confident ( a lot more confident than paper 1) got 83% in my mocks do hoping for an A!

Q1 a-c were fine messed up on part d said he needed 6 flagstones but attempt marks should be grand

Q2
Simple

Q3
Got 5/12 as my last answer, hope this is right?

Q4 -9 simple

Q10
Wasn't sure about the last two parts hmm attempted them but should get almost full marks

Q11 simple

Q12 only part wasn't sure of was e) as I got (0,4) but didn't do a simultaneous equation so not sure on that one

Q13 rounded to degrees minutes and seconds as I wasn't sure what they were so I took a guess attempt marks please!

Q14 and 15 simple

I don't want to lose more than 30 marks on this paper so hopefully ill get my A!!

he prob means the pie one... there is no way 8 was wrong

3yearstudent98

What was wrong with the pie one ? You just had to round it i know it didn't say in the question but it seemed pretty obvious, no?

zubikhan

Are you sure, where in RTE NEWS
I searched it up

Not really, no
It was not that obvious because you are usually told to round of and this time you were not

Monaghan hardy lawd

That's what the news said...or maybe you could say I was...'Lost in Confusion'...Pause for laughs..

spurious

I think it may have been a Leaving Cert. question.

SomberClaws

I can't express how HAPPY I AM WITH THAT PAPER ! I was so upset after paper 1 and thought that my B was gone, but hopefully this brings it up! Im so happy !

Your probably right

zubikhan

Cspe ??....
And there was me all I excited hoping there was an error in maths
Thanks anyways

zubikhan

Why are people talking about Q8 or the pie chart being wrong here, where did they see it

zubikhan

Okay guys I want your honest opinion
I know, like I honestly know that I got around 220-230 marks in the P1
In P2, I would like to know your opinions if I have a chance to get a B at all over all
This is what I got in P2
Q1. I did all of them, but now realising from my friend and here that I did the wrong method and got the answer wrong
Q2. All parts were done and I am pretty confident for full marks
Q3. I probs put down 4 wrong fractions in 4 of the fraction columns, part B I got, part C,I got that as well
Q4. Got all
Q5. Did not even get 1 bit
Q6.Did not get C(I)(II)
Q7. Got it
Q8. Got it
Q9. Got it
Q10.I got A and B but not C and D
Q11. Got it
Q12. Did not get (d)(e)(f)
Q13.Got it
Q14. Got it apart from C
Q15. Did not even get it
So how bad did I do ??

Man the exam is over and nothing you do will change your grade from here on out. Drop Maths and study for something else (Business tomorrow?)

I can't drop maths.
It is my fav subject I got A in the mocks but I for some reasons like hard questions, I seem to always get stuck on easy questions
And trust me business, for me is like taking candy from a baby

zubikhan

nothing you do will change your grade
There is one thing I can do............;)

Oh trust me I know I got a B, it is the fact that I won't accept I got a B, because I wanted an A really badly :L
