    Are there any errors that you made in maths exams this year that you can't seem to get over?

    For me I made a really stupid mistake in AEA Maths.

    I had: [email protected] = 1 and [email protected] = 1 and then proceeded to say R = 1 :|
    Obviously it was Sqrt(2), and also getting a different value for @.
    Thus my solutions to the equation were wrong.

    Really annoying.

    I don't mind it as much when I fail to spot something, I kinda accept it was a lack of ability/intuition for certainly that question, but a silly pointless error like that frustrates me to hell.

    I hope they don't knock off more than 2 marks for that...

    I can remember that in my O Level Maths exam, for which we had to sit 2 papers, and most of my friends scored 100% on both, I scored 100% and 98%. The fact that we were given marks and not grades gives you some idea of how long ago this was...

    I worked out that for some trader, having invested £1000 and made £50 profit, this was obviously a 20% return...

    If I can still remember it after all these years, I think there's a fair chance that I shall never get over it.

    Yes I know what you feeling! not nice. It's lack of concentration so i'm told and it happens a lot to me. It's most irritating when you work so hard then **** up. Inability is acceptable, its those silly things that cost you most at heart.
    ever had 13 marks knocked off for doing e^(-kt+ln20) as 20+e^-kt ?Man i cried for days after my C4. Easiest marks/question on the paper!!!!! I had it in the bag.... argh!

    Some over the summer:

    Show the centre of mass of these wires : Used it as a lamina

    Find the speed of the particle in coefficient of restitution question: Stuck an equation of v in as w...!

    Find the domain: I found the range

    Find the weight: I found the mass


    GCSE papers I did a couple of real gems that cost me a huge amount of marks

    Find the perimeter of a triangle (Given value, given value and x) ..I just found x

    And on another question, I thought there were 360 seconds in an hour.


    Senior Maths challenge 2004

    I thought 23 was not a prime number

    I thought the word cube was the word square

    As you see, I am very prone to lapses in concentration >,<

    And when you're doing the exam, it actually feels as though there are only 360 seconds in an hour...

    That happens when people think to quickly (in a rush) and imagine things...

    You probs thought 5 x 2 to be 5 x 2² =20

    :p: Its good to make mistakes, you learn from them, but not good when in exams :rolleyes:

    well for me : in P4 edexcel: there was something that said: at t=0 x=3 , i used x=1
    and in M4 edexcel: there was a differential equation tht i could had done EASILY, bt i forgot to do the particular integral part

    Differentiation is so much easier then integrating, agree? :rolleyes:

    Doing a practice AEA paper before friday, I lost marks on an algebraic equation becuase of failing to recognise you get spurious answers when you square the equation.
    I took heed of my mistake. Then during firday's AEA (Q2) i did the same thing, got to the end and (quite literally) couldn't be bothered checking for spurious answers, i.e. 13pi/12 17pi/12.
    So that'll have cost me about two marks and tbh I need as many as i can get, because I reckon I'm pretty borderline on 'merit'.
    So I'm relying on getting about 4 'S' marks, as well as a few for working on questions I didn't complete.

    Does anyone know:

    a) When they say 'S' marks are awarded for questions fully correct in principle blah, blah blah...I assume they are talking about full questions i.e. Q1. Am I right?

    b)How much the 50% grade boundary can fluctuate, if at all?

    A fluctuation of 0.7 standard deviations from the mean, relative to the other grade boundaries, which is not a lot of fluctuation. :p:

    Given the difficulty of the paper would everyone agree that the grade boundary is more likely to go up than down?

    But it can't go up too much - only a few marks at the very most, surely?

    I'm just after a distinction that I wasn't expecting at all before the exam. Just about every one of my answers agreed with other people on here :tsr: (bar silly mistakes that will cost one or two marks such as thinking tan¼πsec¼π = 1 or something). I don't want the boundaries to go up .
