    would 67/75 on C3 and 62/75 on C4 be an A?
    Almost certainly

    doubt it'd be over 95 really
    From the papers I've got here which I did as revision:
    C3 June 15 - 71 raw -> 100 ums
    C3 June 14 - 70 raw -> 97 ums
    Wouldn't be surprised at all if it was over 95, did you really find C3 that easy?
    I know people who are pretty good at maths who couldn't do some of the questions on there

    I know this is the C4 thread but it's more active than C3 so thought i'd ask my question on here for C3:

    if on the last part of the last q on C3 (where you had to show that T=...) i had T= -5ln(1/2+.../e^1.4) would i get 1-2 marks? The inside wasn't tidy or what it was supposed to be but i got -5 on outside and half on inside so cause of ln rules it's the same as having 5 and 2 ? (my inside wasn't correct but i showed working to get the value for a)

    I believe you and me made a similar mistake. I think we missed out multiplying every term by e^-2/5 or whatever. I can't remember my exact expression but it wasn't right, I am expecting to lose 2 or 3 marks (it was out of 4 I think).

    Yeah it was out of 4, i think the least we will get is 1, maybe 2 if we're lucky but say 1, i also didn't leave one of the answer in simplest form earlier so expecting 71/75. Any guesses what UMS this would be?

    would 66/75 in C4 and 72/75 in C3 be enough for an A*?

    exactly what im trying to find out, realistcally we are both on A, providing you got very high in c1 and c2 and at least C's in the applied, but that A* would be very nice especially since we did better in the harder paper :') even if someone were to say that we would get an A* it wont be guaranteed, so i think we will just have to wait but we should enjoy the summer in the mean time.

    Yes, highly likely. 72/75 in C3 will fetch you 95 UMS atleast, if not more. 66 on C4 will fetch you atleast 85 UMS (but again, more likely to be more than that)

    Nah, theres no way boundaries will be like January 2011. Most people on this site are claiming A to be around 63. There is a proven historical pattern of grade boundary overestimation on this website, due to the majority on here being at the higher end of the bell curve. So chances are an A will be 61 or 62.

    I dunno I got the same I think. I reckon 95 will be minimum, as 71/75 is 95% raw and tbh I wouldn't be surprised if it's higher because it was fairly tricky imo
