    15,000 is P I think? Because it is what he initially borrowed.

    No see I'm just setting P as the value of the monthly repayments and using future value figures which should add up to 15k... It makes sense in my head but I've seen a lot of different suggestions :/

    Yep! :D

    Ye that was a simple q. They made calculus quite long

    I think you're kind of mixing up the amortisation and geometric series way.
    P, as stated in the log tables, is the principal. Your way would be fine as long as you used a geometric series formula and not the amortisation formula.
    Also, I would believe you'd have to use present values as they need to add up to 15000

    Are most of the marks for the long questions, usually given for the first few parts? Like a part e might only be worth 5/50


  • Registered Users Posts: 428 ✭✭Acciaccatura


    Nope only the basics as you said. There seemed to be more of a focus on recognising graphs

    Oh thank God, I thought I'd done something terribly wrong, which I have a tendency to do :P Do you feel we had it easy? Personally I'm rather thankful of being in a pilot school, the calculus on the other paper looked like Mandarin :D


    ...I'll probably eat my words on Monday evening...

    For the tickets question you cant assume that all the €16 tickets were sold you had to make up some simultanious equations and use them to find out the final answer was actually 2500

    ya it took a fair bit of time and effort but probably only five marks

    How many ppl mistakenly though q3 said to two digits instead of significant figures... it almost caught me again

    I left it as 8916 by mistake :(

    what were you supposed to say? 8.9 x 10^3 or something?

    That hasn't been decided yet, unfortunately. They decide where to allocate the most marks to when they do up the marking scheme. I've heard that last year most of the marks where weighted towards the earlier parts, but we'll just have to wait and see. :)


  • Closed Accounts Posts: 2,827 ✭✭✭Prodigious


    Thats the part I'm delighted apart. Got most parts of the paper. Did loads for the last part of 5 and 6 but got the wrong answer on both. Still have a solid chance of getting an A because they'll most likely manipulate the marking scheme and the last parts will be worth sweet f*ck all.

    did anybody else do the answers on the white paper provided instead of the pink exam paper there is a serious panic going on here. thanks

    As long as you labelled the answers correctly, it should not make a bit of a difference.

    The SEC stated:

    Marks can be deducted if answers are done on a separate booklet.

    But I really doubt any examiner is going to actually deduct marks for it, realistically speaking.

    Sorry I mixed it up when I was typing it there :P I did mean present values not future hence why I denoted the repayments as P... and yes I used the sum of a geometric series I never bothered to try and understand the Amortisation formula, a foolish mistake in hindsight :L I think I worked it out but don't understand why it's that way :(

    Did people get something of the order (y-2)=-2(x-2) for parametric

    I am a LC superintendent. We were clearly told at the conference that candidates are allowed supplementary paper. This is also clearly stated in our handbooks. You may not, however, answer in an official exam script.

    Supplementary yes, but our teacher told us that at the conference she was told you cannot just decide to do the whole exam on different paper.

    What does the bold part mean?

    I used the ammortisation formula for both the financial math questions.. Was I right?

    The exam script - the pink one. I don't think anyone was misguided about having to fit as much as possible onto the exam paper - that was also clearly communicated to superintendents.

    No, only on the exam paper or on supplementary paper if required.


  • Registered Users, Registered Users 2 Posts: 236 ✭✭SecondMan

    So we were only supposed to write on the exam script but we are not supposed to write on the exam script. Oh right


  • Closed Accounts Posts: 2,827 ✭✭✭Prodigious


    Right, I'm totally confused now..

    What's the difference between the exam script and exam paper? We were given a pink booklet which had questions and boxes to answer in... What's that one called?

    The only thing we were offered was supplementary paper, which the examiner stamped, and this was white.

    Yes, what you did was correct.

    The exam paper has the questions, which - in the case of Maths - you're also expected to answer in.

    The exam script is the booklet where you write your responses. You used this to write your English answers, for instance.

    For the bit where she was saving money every month I did it both ways and got two different answers.
