OL Maths paper 2

Cook!eMonster

anybody else think it was simply AWFUL?

Shanotheslayer

Thought it was reasonable easy.

Got stuck on Q3 B/C

everything else I gave a solid attempt at

James_LWAU

taught it was ok just ok say is just scraped a pass couldn't answer question 3 just wrote down a whole load of formulas

Cook!eMonster

ugh no i hated it, if i passed it would be a miracle, seriously. and Now irish, i need to cram for business tomoro!

hahah yeah same
i couldnt get b but i got c no probs
i was happy with it
imo went better than paper 1

i think im gonna get full marks in the stats q1 and vectors
they were great

Finical

Handy enough I attempted nearly everything apart from odd one or two. Probability caused me most problems.

RyanK

That was a very nice paper. Q 3 B caught me out but I made my own answer up for that for maybe an attempt mark... Apart from that, I did pretty good. Makes up for the crap Paper I

Princess3

It was mostly alright but some parts were awful like Q3 B, i didn't have a clue. I think i messed up a bit on Q7 as well but the rest seemed to go ok for me Probability got a bit confusing though.

Mau5

I thought it was good enough!
absolutely nailed Area & Volume and Linear programming
trigonometery was dodgey though

highlydebased

Nice paper I thought. Should have got high 30's-low 40's in most the questions. Happy now

dannydfc

I say/hoped i passed.
it wasn't the worst of papers but it had some tricky enough elements.
one of the question , i think it was 3 was awful.
irish should be relatively easy, i hate the tape work though.:(
I'dd defo be cramming all night with business too.:eek:

Irish Paper 2 + Business tomorrow.

Same for me! Need to cram when i get home today!!

Fete

There were some snags but I think I did really well. Messed up C i) of vectors though.

MonTheBiffy

90% easily that has to be on of the easiest exams iv ever sat i waited right till the end and only droped at most 10 marks i might sound cocky and it may come back and bite me on the ass in August but i aced that! good luck to everyone in Irish later doubt it will be as easy

dannye92

thought that that was very easy this morning

dreadin irish..im screwed!

Indeed...after that it's not too bad for me though.

ldxo15wus6fpgm

Thought it was very easy. Forgot how to do the last part of Q10 though, got 2/15 by messing around with the calculator but I doubt it's right :rolleyes:

dannydfc

What are the opinions on the graphs??
I thought the histogram and the frequencey curve questions were easy.:P

But for the question 11 , i just drew graph put in points,plotted a few points, and guessed that teh arrows were going inwards and then shading the inside part.
anyone get that one???

Thought that was a fair enough paper. For anyone who couldn't get Q3(b) I think this is right. you had to let x = 4y + 17 then sub it into x2 + y2 = 17 then just solve it and get your quadratic equation and the factorise to get x and y and thats your point. Then for the second part you could do it by translation.

Lawliet

I thought it was alright over all. Q2 part C threw me a bit, Q 7 and 11 were wonderfully straightforward and the rest were pretty average

I've bolded the answers I have that are different to yours...

2b iv I got 4x+3y+5=0
5b iii I got 8/17 you've put in (A/O) instead of (A/H)
5b iv I got 240/289, what you've done there is got 2 sin theta instead of sin 2theta
5c ii I got 39m, I think this came to something like 38.467, a lot of people rounded down to 38 after looking at the .4, but it should have been rounded upwards to 39.
6b iv I got 1/2, I'm not too sure if i had my methodology correct here though

FlawedGenius

I ran out of time!!!. I didnt finish Question 7 and didnt attempt any question on Section B.:mad::mad::mad: The questions I left till last were draw the cumulative frequency curve which is easy and get the median score. Also didnt have time to get the standard deviation. I was doing really well up till then:( Done terrible on PAPER 1. I reckon if I had of finished question 7 on Statistics and even attempted a question on Section B Id have passed. Gutted:(

Did you round down on part B? other then that I think I got all them!

Reckoner91

Wow, way to completely f*ck up the maths exams. Make Paper 1 way too hard and Paper 2 way too easy. What's the deal!?

dentalnurse

How many marks between the two papers do you need to pass??? Out of the 600??

240/600 is 40%. Simple maths.

dentalnurse wrote: »

228/600 = 38% which is the pass mark in maths according to the maths teacher john brennan on countdown to 906

RyanK

Ah yes, forgot that it's 38% for maths.

mr_paddy

love that paper better than paper1 for sure:D Q11 Q1 was so handy then went flying with the rest got stuck for time for Q6 but most of it done hopelful i pass

Ah NO! Those are such silly mistakes :( I think my 6b iv is right, I thought hard about it!! Hopefully I wont be marked too harshly for them mistakes....though my answers are wrong LOL . I guess thats number 5 which won't be counted! I'm glad I did all the Q's :cool:

Did I round down in Q5 is it ? When I said 38 ? Ya its ment to be 39
But wooooo go us ( assuming that the 3 of us have'nt all made the same mistakes and gotten everything wrong )

I meant on Question 6 for the probability:/ I was stuck between 2 ways in how to do 6B probability:/ Hopefully did it right

Oh! How did you do it?

Shanotheslayer

I'll get back to you on that mate! I'll have a look now and Pm you.

Shanotheslayer

For B(ii) I got

10/25 +(or x) 9/25= Im pretty sure I should of done 9/24 though:/

I really can't remember:s

iWeeze

Think I should get close to 50 in 1, 2, 6, 7 and 11.
Only thing I didn't do was part B on 3, hadn't a blue's clues.

0.M.GXX

i am tOtallly with you there.. i thought it was awful.. even though every 1 thought it was easy... im jus hoping some how ..i manage to get a C3.. uttterly sad...:(

STBR

Sorry not meaning to be cocky or anything but WHAT a great paper. Almost certain I got 100% on that!

Did 1, 2, 3, 5, 6, and 11.

7 looked good but I was so sure of the others I spent the time going over them.

Joseph

Just on 5 C (ii), you won't loose marks for rounding it down if you were rounding off as you went and thats why you ended up with 38 like for me

Viva La Cozzy

went alot better than paper one anyway..are and volume was one of the easiest questions i've seen in years...way easier than the pre...i say i got full marks in it, and i usually mess up part C in that question...I had to do so much cramming to learn most of the stuff off though, i was expecting to wake up at 7 to study this morning but i didn't wake up till 8 i only got a glance in at vectors so i messed up part C...couldn't even attempt it part A and B were handy though so i mot likely passed that question

I think I got 18 but no remender? Can't remember though. I'm fairly sure I got 630!

And 9C 100% confident its 0=0 dot product= 0 that R is perpendicular to S or whatever the letters were:)

And for all of 9B I used graph paper.

Completely agree. I came out so happy. It was really easy imo, but I guess its like that when you do honours for most of the leaving cert 2 years.:D:D

Orlaladuck

Delighted with it - it was almost perfect except for 3B and the probability was a bit 50/50 otherwise it was grand, really happy with it

Sl!mCharles

Yeah probability was tough, usually a bit easier i thought!

*giggles*

Much better than Paper 1 I thought. Not as tough as other years. Linear programming went well, didn't like Question 2 or 3. Other than that, pretty happy.

Victoria.

I was pretty pleased with that paper.
From looking at some of the answers on here they look familiar anyway.
I did 1,2,3,5,6,11
No major problems didn't get the last bit of 11 because I was rushing and did trig at the last minute and I got one part wrong I can remember.
Was happy coming out much better than paper one.

toto14

so happy with both papers!!! should get an a ...i dropped from honours last year tho so dont feel bad if you thought it was hard....a lot in my school werent happyish i think

Had these myself. Bolded the ones that seem to differ from other people's.

3 (a)(i) 13 (ii) x^2 + y^2 = 169 (b)(i) (17,-4.25) (ii) (-17,4.35) (This looks wrong. Should get the marks for the second one though) (c)(i) r=10 C=(1,-7) (ii) h=15 or -1

5 (a) 11 (b)(i) 8 (ii) 15/17 (iii) 8/17 (iv) 0.8304 (c) (i) 27 (ii) 21
