Maths Paper 2 OL- how'd it go?

Corruptedmorals

Grand paper. Did area, line, probability, trigonometry, statistics and linear inequalities. Area was easy, line was grand, trigonometry was almost too 'Look, use this formula here'. Couldn't get part of b, but a and c and the rest of b were fine..Probability, full marks, and statistics, grand, except I forgot what median means...

Linear Inequalities question was messed up. I normally get full marks on them, but the way this was phrased threw me completely, couldn't get it to work at all. So 10 marks for part A of that. I calculated I should get about 80%, so with paper 1..71% or something like that.

Easy enough though, what did everyone else think of it?

Enemy Of Fate

Meh.It was grand enough I guess.Oddly enough in 2 or 3 questions I had more problems with the B parts than the C parts!Anyways I'm pretty sure I got full marks on statistics and probablity, and the majority of the marks from the other 3 questions I did.....However I did **** in the linear equations question.Probably got A wrong, and only attempted B iii (which was ****.ALl I wrote was ''to minimise construction costs, only apartments should be built''....I mean they cost less so of course it'll minimise costs!!!).Was there actually a problem with the question?Didn't seem to make sense.Ah well.I'm pretty much guaranteed I got my C3, and thats all that matters.

linear programming sucked alright, 11:55 i worked out how to do it and as im in my own exam hall my examiner allowed me to stay till 12:15 to rush it off

Basically it was
A developer is planning a holiday complex of cottages and apartments, each cottage will accomodate 3 adults and 5 children and each apartment will accomodate 2 adults and 2 children
3x + 2y <= 60
5x + 2y <= 80

once you have those 2 inequalities then the rest becomes easy, because i rushed off the question so fast i doubt i got full marks (like i ussually do for those questions). Rest went pretty good though


Edit: I was in such a rush that i said only cottages should be built, aargh :S

anyone have answers to probability please!!!

Q10 C(i) A compound interest Q ???

Seemed very easy

Q10A- .20 or 1/5 .. easy

Steve01

I got on well I suppose. Aced questions 1, 5, 6 and 7, could well have gotten 50/50 in each of them. Probably got 30-34 on questions 2 and 3, whichever one got the higher mark will be counted obviously.

It looks like I'm not the only one who was annoyed by the linear programming question. It was confusing and poorly phrased to say the least. I spent about 10 minutes just reading the damn question and I still couldn't figure out what they were asking for. I eventually used the equation that grouped adults with adults and kids with kids, which is what a lot of people have done so hopefully I got the question right. The rest of it was easy once I got that sorted.

I'm not counting Maths for points but I'm still hoping I got the A1

I got €2531. For part (ii), I got €14387. Not sure if they're right though.

What'd people get for the Simpsons Rule question?

justbringit89

Simpsons Rule was 50 Squared

Haven't a Clue

Yeah, thats what people were saying. Must've slipped up there somewhere along the line.

AdMMM

I can't get over how the Linear Programming question was worded. I must have spent about 30 minutes trying to figure it out! It's usually my best question and I turned over to do it first but by God that was the strangest and hardest Linear Programming question I have ever come across and I usually aim for 50/50 in those questions. I was pleased with the Area and Volume, Probability and Statistics questions but I'm still upset about the Linear Progamming. I need a C3 and I'd be gutted if I didn't get it because of that question!

Those who I talked to in my class felt the same, so I hope that they adjust the marking scheme, although I can't see how it can be adjusted to award my incomplete and incorrect graph any marks . I hope someone in the SEC loses their balls over that question!

izzyflusky

I thought it was sooo easy. I feel better after my fiasco in paper 1.i think i messed up a small part in question 7. But the rest was ok. N didnt think question 11 was hard at all. I prob had small mistakes in general that i cudnt c at the test..but other than that i tink overall was the easiest test in years

ash_78

i am seriously bad at maths....felt alright about p.1 but my confidence is totally dropped since p.2......could someone plz relieve my mind and let me know, what is the minumum to pass...like which and how many questions, parts were necesarry for a d3?

Same as that. The very last minute I copped to group adults with adults, mad rush altogether. Very poorly worded question, they might change the marking to accommodate this? Hopefully?

Each question's 50 marks, so you'd want an average of 20 out of them to pass. You'd wanna be doing, at a guess, the a parts spot on and doing reasonable attempts at the others to pass.

fallon54

Piece of piss, easily 270 out of everything at worst. theres my A1 anyway!!

Agri_trust

I think it went ok for me. Probabilty seemed so easy I thought I was doing something seriously wrong.


Didnt have a clue of the liner programming, so I did the geometric series question when I seen the compound interest part... I ended up ****ing that up to.

Rest of the paper was very easy though.

Agri_trust

Did anyone hear that you need just 38% to get a D3 or something?

It was on that leaving cert program on RTE?

yeah thats true , i think it even may be 37% !!

Ok I done the area Thing

supposed to be 1/2 (x1y2-x2-y1)

now i done that except forgot to half it ??

will i lose much marks(could be the difference between me repeating or not)

My best bet would be that would be a deduction of 3 marks for a blunder: "This is an error in methodology or using a wrong formula".

Jayeire

Not a bad paper at all I think, vectors remain my only concern

óbriain1988

unless ya man has to build 12 and a half cottages and 2 and a half apartments to save on the construction costs... i think i might've messed that q up. it was ok otherwise though, trig was fine and that. thankfully i'll never be in a situation where i'll have to work out maths problems again...:p

Jay112

Went okayish! messd up 3rd part Q1, simpsons rule was simple! Q2 went okay and had trouble with part 3 of Q3, 6 and 7 went okay! and i needed to think about Linear Programming! delighted I ended up getting it right, both lines clashed at (10,15) did everyone else get for it?

sdanseo

Brilliant paper given I didn't bother going over Vectors or Probability. Did Q1,2,3,5,7 - couldnt do the vectors question but still got a good C1 on the paper. Q1,3 and 5 were piss easy for me, maybe half marks on the other two.

Yep I got (10,15) too

Evd-Burner

The linear program end part was kinda funny the way it was worded, it was saying u ahve to choose some of both x and y, sure all ya have to say then is build one of each ,they will have to adjust the marking scheme for that question as it was very hard...

Over all i reckon i did pretty good in the paper

mang87

In comparison to last years, it looked like foundation level stuff.

They didn't really ask anything too difficult, some of it was so unbelievably easy and obvious it didn't even require too much maths.


And here I was stressing, I feel fantastic now.

Heh, I've just to worry about biology tomorrow, I still don't know anything about it.


French - easy.


Then I've a WEEK off to study for chem, but ofc I'll just celebrate early and then study for it the night before. Pass chem is a doddle. :cool:

Yea iv got bio tomorrow aswell! going to be tricky as usual!! are you in honours or ordinary Biology?

mang87

Did honours last year and its the reason I'm repeating, so I'm not going to chance it.

cabla

That was easy enough i thought...Did like 1 hr 30 for revsion for it...
Line and circle were only places i say i lost marks..only a few though.

I thought the linear was grand...Very handy in my opinion, but i can see how people got confused...I also got confused at one thing...anyone get build apartments only for most profitable??

Jay112

some lads had (16,0) for the less costing construction!me on the otherhand been the plank i was said (0,0)

Lol your right though...but ye it is (16,0)

I blame my techer with the whole Conspiracy '' trick questions '' he tells us could come up lol wait till i get a hold of him

Haven't a Clue

Haha. Apparently question 2c(ii) (I think) was meant to've been the same as the question 2b(ii) in the junior cert. God I love ordinary maths..

pilchard

Does anyone have an answer, they think may be right for Q2 Cii) i got (8,11), but found the question strange....

Haven't a Clue

I got (-8,11).

Lol techincally you're not wrong! I don't see how they could mark you wrong. There was no 'some must be built' or any fancy wording around it.

I had it written down and all but changed it. What kind of financial advisor would say, 'well, to save your expenses, don't build the thing, fool!'

kurisu

3 of my questions seemed absolutely perfect(seemed! im not promising anything) the oters where ok until Q11 (b) which i had 1/2 hour of decoding the question and trying to prove i knew how it worked in the end all i had was some strange atempts at divding people into cottages, if i could have figuured out the two equations to start the question it would have gone perfect the rest of the way, many of my classmates complained about Q11 (b). And to think (a) had gone so well

i had (0,0), but then i added 'assuming something has to be built, then- 16cottages and no appartments'.. so i dunno, it was one of the few ambiguous questions, imo

pilchard

The other ambiguous question, according to a friend, was Q6 Ciii). she answeed that:
all of the numbers made are devisable by 5 just not all of them devide evenly....
we're all thinking that it probably wont be marked correct but.. the question does not specify that they have to devide in evenly.:)

Yeah. Hard to argue against her I suppose. If she ends up dropping a grade because of that answer, make sure she gives out ****e about it.

spiderman1885

I did Qs 1,2,3,5,6 and Vectors! The vectors Q threw me at the beginning but it was ok a few minutes later.:D
I reckon a got an A2 at the very least...kinda makes me wish I had actually put work into maths and done honors!:mad: Woulda meant i could of done way more college courses i wanted to!

Dean-16

il be lucky to get over 55% overall> paper 1 was much easier imo!

Naikon

Yeah, paper one was real handy in comparison I must say.
I really liked the probability question which I was ****ting over before the exam:/
Dont try predict, you dont know the marking scheme and wont until August 15th.
The Linear programming question better be marked easy:mad:

Limerick Dude

That was a great paper!!! I hope it will push me up into the A zone as my paper1 was a wee bit muck!

Gossip_girl

Paper was grand for me but thanks to linear programming theres no way i'm getting an A1 now Did question 1,2,3,5,6 and Q11. I figured out how your actually meant to do it in the last 2 minutes but i didn't have enough time to re draw it! I hope to god they change the marking scheme cause otherwise i'm gonna have to repeat!
