    Did anyone find the CIE PAPER3 spec paper particularly difficult?? (or was it just me? )
    of course well it's supposed to be the advanced version of paper 1 so of course it's going to be harder. But the kind of questions it asks are actually quite different from the TSA, so i'd focus more on the paper 1 if I were you.

    the 2007 Paper Q13:
    It takes 12 men 2 hours to dig a hole two feet wide by two feet deep, how long will it take 6 men to dig a hole twice as long, wide and deep?
    a 32
    b 8
    c 64
    d 4
    e 24

    please help....

    12 men: 2 hours, 2 ft wide, 2 ft deep, y ft long
    6 men: x hours, 4 ft wide, 4 ft deep, 2y ft long

    For each part the men will need the double amount of time.
    This basically means that you've got 4 times the factor 2. (12/6 ; 4/2 ; 4/2 ; 2y/y)
    2 hours * 2 * 2 * 2 * 2 = 32

    42 There were 5 competitors in the school’s Victor Ludorum competition to select the best athlete. Competitors competed in up to 5 events. The scoring was 5 points for the winner down to 1 point for the 5th place. Anyone not competing in an event scored no points. At the end of the competition, a contestant’s worst event was ignored and the sum of the points for the best four events calculated. The winner was the highest scorer.
    The table below shows the finishing places in the five events:

    ..............High jump 100m 1500m Discus Long jump
    Chang ..........4........ 5...... 2....... 1........ 4
    Costa ...........5....... 3...... 1 ........5........ 3
    Deschamps.... 2....... 1.... DNF....... 3........ 1
    Khan............ 1....... 4...... .4........2 .........2
    Smith ...........3....... 2...... 3........ 4....... DNS
    (DNF = did not finish, DNS = did not start due to injury)
    Who won?
    A Chang
    B Costa
    C Deschamps
    D Khan
    E Smith

    Ok:

    The first hole's volume is: V1 = 2ft * 2ft * y ft = 4y ft^3
    ................................ ..........wide..deep..long

    The secons hole's volume is: V2 = 4 ft * 4ft * 2y = 32y ft^3
    ................................ ..............wide..deep..long

    V2 / V1 = 8

    So the factor for the hole is 8.
    12 men would need 8 * 2 = 16 hours.

    But there are only 6 men. They will need the double amount of time: 2 * 16 = 32 hours

    Now?

    They say anything over 80% (40/50) is very good. Stop worrying^^ I personally just did the 2008 one, ran out of time and so I often end up in the low to mid 30's which is like 65-70%
    dont worry, this is similar what i got. i just saw lots of people getting 40s or above which worries me and makes me feel inadequate. i only got 36/50 on the 2008 one.

    Guys the tsr average will definitely be above the average for the applicants nationwide, mid to high 30s im pretty certain will be average at the least.

    I think this is how it works:
    12 men take 2 hours so we presume that 6 men will take 4 hours
    To dig a hole twice as wide take 8 hrs
    Twice as long as that takes 16 hrs
    Twice as deep as that takes 32 hrs.

    So the answer should be A: 32 Hours

    I hope that is the right answer/makes sense...

    Just done my first actual paper and am pretty happy with my mark, will do the others in a bit. Hopefully the essay'll go ok. I have to do well to compensate for the rest of my app so it's a bit annoying.

    Jason left Ranjiv’s house yesterday afternoon, walking home at 5 kilometres per hour. Ranjiv
    quickly discovered that Jason had left his mobile phone behind and, 6 minutes after his
    departure, set off after him on his bicycle at 25 kilometres per hour.
    How far had Jason walked when Ranjiv caught up with him?
    A 375 metres
    B 450 metres
    C 500 metres
    D 600 metres
    E 625 metres

    Get the answer right but my working out is weird

    I can't be bothered to check but is 49 the one with the energy costs?

    I got this wrong too - but after checking it I think they also included the cost of the logs for fire...?
    Yeah that's the one - I didn't realise at the time that logs of fire would have counted as energy seeing as it was separated from electricty and gas

    I was pretty anxious whether in the end something will happen to Mr Toast and I'm not disappointed.

    Oh, and I have found a real jar full of cookies.:woo:

    Ten Thinking Skills CIE question papers ( the latest ones are exactly in the TSA style):

    And the mark scheme:

    At least I can't say now, that I don't have enough TSA tests to practice

    Another question: From CIE Thinking Skills June 2005

    The cog sizes and chain length on a bicycle are designed to even out wear, so that the same hole in the chain does not encounter the same tooth on the cog in every revolution. The chain wheel (front cog) of a particular bicycle has 48 teeth, the rear cog has 18 teeth and the chain has 90 holes.
    How many revolutions must the front cog do before the chain and both cogs are back in exactly the same relative positions (i.e. the same holes are encountering the same teeth on both cogs)?
    A 5
    B 8
    C 15
    D 20
    E 30

    Jepp, I understand I forgot to add the long... stupid mistakes -.-
    Thanks!!!

    Another one.... can anybody explain the algebra for these age-questions?

    I can´t find them anymore :confused: But it is e.g. the one with 10 years ago, Jane was 2x Marys age, 5 years ago 2/3 (?), Daisy is 3 years older than Mary (or Jane?)...How old is Daisy today?

    I am sorry I was searching for these question, but I really couldn´t find it... I am at the airport now...have to leave now, but wanted to ask before I am going ^^

    Hope someone knows which one I mean:yes:

    Thanks again
