    For the first part of 8 I got x=(5/4)[1-1/5(1+t)]^2 - 4/5. Is this correct or not?

    Do people think that 75/75 in Core 3 and 61 or 62/75 is enough for an A*? ...Really panicked in today's exam, despite aceing core 3 and doing well in past papers :/

    Everyone happy with the mark scheme now?
    On 8bi, does the k and the pi cancel to give a different constant?

    Probably 1/2 for the marks on the alternate method (This will not be the main method, but they will have an alternate one!)

    looking at the mark scheme, i think i hit 65/75 (made some stupid errors because i just blanked) but i'm going somewhere between 60-68/75. what grade do you think this would be, roughly, and will this and 68-ish/75 on c3 be enough for an A? thanks

    I hope so!! It would just scrape 90% over c3 and c4. You're exactlky the same as me - think c3 was maybe 75 and c4 58 - 61 Spent too much time on the earlier questions and so didn't do as well on 2nd half :/

    Not sure! I get your point but I think they were looking for pi in the equation to show you know the area is pi r squared.

    I could show you if you like

    although, I can't remember what I got in the actual exam, so I sure hope I wrote 1/4
    thanks, but I made a mistake ( i did edit it), it was suppose to be q7b)

    No, saying they "cancel" is mathematically incorrect. Instead, because you know k is a constant and pi is a constant you can combine them to make a new constant.

    I wrote 2 pages of working for it.

    Then scrapped all that and added 1/2 AC and 3/2AC onto B :/
