    Last year the A* boundary was 82% and the A boundary was 64%. I've just looked through those papers and they were easier (I think) than our ones so I guess the A* boundary will be lower this year then?

    both solutions worked out so you will probably lose one mark (can't remember what it was out of). I found paper 4H much easier than 3H although I didn't find either of the papers particularly hard, they just required you to concentrate on the questions more than you usually would. I agree with you with regards to the grade boundary not going below 79, I think it will be around 81-82 on account of the "easier" paper 4H.
    ahh right ok, well it was out of 5, and even with that mark lost looks like im on for about 84/100 on paper 4H and 81/100 on paper 3H - enough for A*? and yeah i mean last question had me fooled on 4H but i just wasnt concentrating enough for both papers sadly. yea i dont think it will go to 82, as that was June 2011 grade boundaries and those sets were amazingly easy, but yes somehere between 79-81

    they are generally OK with Graphs being in pencil, but working out and stuff must be in black pen! and dont worry if youve done it all in pencil, i heard that instead of getting 0% your paper gets sent back and you go over the pencil with a black pen with a dude looking over your shoulder, then you send it back for marking? i heard this is what happens but not sure
    they will just not mark it electronically, but mark it by hand,
    are you mocking this guy or just dumb?

    Thank you for putting trust in me; give me a rating and here goes the blank (raw) copy of the paper (check a few posts from now and you'll find the paper). Kaur will solve it in the next few hours and we'll have our estimated grade boundaries as well as the answers

    no im trying to be of help to him, i was not aware that they mark it by hand as this is just what i heard - i dont particularly find your comments useful at all, havent you got something better to do than to come on here and just berate people for the fun of it?

    no from sam's house back to his house was 40km and time was like 1.25 or something so 40/1.25 is your answer s=d/t
    (Original post by gabriel 41)
    It was 39 km and 78 min; I don't know how you've got 40 km
    It was 39 km and 75 minutes (as he left at 16:00 and reached home at 17:15).

    Ok I got 190 as well don't worry; let's hope it's not 200
    Dude I swear the histogram question was something close to 20% and you get like 200 something people. The only possible way to calculate the percentage is by counting the squares which is really really stupid.

    For this question I did volume of 2 spheres + volume of empty space = volume of cylinder. Please tell me whether this is right or wrong. :confused:

    Because when I solved the equation like that I yet got r=2.5. So my method is right isn't it?

    Yeah, wasn't it 90/500 squares? Which would equal 18%

    yea that is right it was definitely 18% ( i originally made a silly mistake and got 22% lol, but then checked it and edited :P), there is no way aswell the total people was 190, it was definitely 200!! 0.4 people a square, multiplied by 500 squares gives 200

    How is last question 2.5 ? I done volume of cylinder - the volune they gave = 2[sphere volume]
    Then rearranged to find r ? And u got 5.36
    because the question says the volume of the cylinder without the spheres is 125/6 pi or something. So in the equation you have to add the volume of the cylinder to the volume of the spheres. So its something like pi r squared h = 125/6 pi + 4/3 pi r cubed * 2.

    I'm pretty sure it was 3.6 large squares / 19 large squares which gave an answer of 18.9%. Is this what you mean when you say you got 18%?
