Cook!eMonster · 14-06-2010 11:04AM #1

anybody else think it was simply AWFUL?

Shanotheslayer · 14-06-2010 11:08AM

Thought it was reasonable easy.

Got stuck on Q3 B/C

everything else I gave a solid attempt at

James_LWAU · 14-06-2010 11:10AM

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 · 14-06-2010 11:13AM

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 · 14-06-2010 11:21AM

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

RyanK · 14-06-2010 11:23AM

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 · 14-06-2010 11:23AM

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 · 14-06-2010 11:23AM

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

highlydebased · 14-06-2010 11:27AM

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

dannydfc · 14-06-2010 11:28AM

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:

Finical · 14-06-2010 11:32AM

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

Fete · 14-06-2010 11:34AM

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

MonTheBiffy · 14-06-2010 11:34AM

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 · 14-06-2010 11:34AM

thought that that was very easy this morning

dreadin irish..im screwed!

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

ldxo15wus6fpgm · 14-06-2010 11:45AM

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 · 14-06-2010 11:56AM

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???

Philly_C · 14-06-2010 12:05PM

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 · 14-06-2010 12:09PM

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 · 14-06-2010 02:09PM

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 · 14-06-2010 02:29PM

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 · 14-06-2010 02:48PM

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

240/600 is 40%. Simple maths.

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

RyanK · 14-06-2010 02:59PM

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

mr_paddy · 14-06-2010 03:26PM
